Cationic Polymer Series

What is Cationic Polymer Series

A cationic polymer is a long chain of millions of carbon atoms on which positively charged spots are attached around the perimeter. The positively charged spots act like tiny hooks to attract negatively charged particles. The cationic polymer brings all the tiny solids together to form much larger masses.

Poly Dimethyl Diallyl Ammonium Chloride Market Insights

Poly Dimethyl Diallyl Ammonium Chloride Market Size was valued at USD 1.5 Billion in 2023 and is expected to reach USD 2.9 Billion by the end of 2030 with a CAGR of 10.7% During the Forecast Period 2023-2030.

The market for Poly Dimethyl Diallyl Ammonium Chloride (PolyDADMAC) comprises the worldwide commerce and utilization of a cationic polymer that finds application in water treatment, paper manufacturing, and other related sectors. Diallyl dimethyl ammonium chloride monomers are polymerized to produce PolyDADMAC, a quaternary ammonium compound with a high molecular weight and exceptional cationic properties.

PolyDADMAC is essential to the purification process in the water treatment industry. It helps remove color, suspended solids, and impurities from water through the processes of flocculation, settling, and coagulation. Because of its positively charged nature, it can effectively bind with negatively charged particles to remove them and purify water for use in both municipal and industrial settings.

Dimethyl Diallyl Ammonium Chloride and Diallylamin Co-Polymer Modified Bio-Film Derived from Palm Dates for the Adsorption of Dyes

For the first time, co-polymer of dimethyl diallyl ammonium chloride and diallylamin (PDDACD) was used to modify the films derived from the waste of palm date fruits, which were then investigated by the purification of colored aqueous solutions. The physico-chemical characteristics were identified using data color, FT-IR spectroscopy, and SEM features. The modified films were evaluated as adsorbents of Methylene Blue (MB), Direct Yellow 50 (DY50), Reactive Blue 198 (RB198) and Naphtol Blue Black (NBB). High retention capacities were achieved in the following order: The equilibrium da DY50 (14 mg g−1) < RB198 (16 mg g−1) < NBB (63.9 mg g−1) < MB (150 mg g−1). The kinetic modeling of the data revealed that the adsorption data follows the pseudo second order model. It was fitted to the Langmuir, Freundlich, Temkin, and Dubinin-Redushkevich equations, and the data best fit the Freundlich model indicating that the adsorption might occur in the heterogeneous adsorption sites. These results reveal that PDDACD modified films are valuable materials for the treatment of industrial wastewater. Moreover, the as-prepared adsorbent is economically viable and easily controllable for pollutant adsorption.

Application of Poly (Dimethyl Diallyl Ammonium Chloride)−reinforced Multifunctional Poly (Vinyl Alcohol)/ Polyaniline Hydrogels as Flexible Sensor Materials

The design of multifunctional hydrogel sensor materials with comprehensive properties such as frost resistance, good reusability, adhesion, and flexibility needs to be developed to meet the demands of complex environments. Herein, a conductive, semi-interpenetrating network hydrogel was constructed from poly (vinyl alcohol), polyaniline (PANI), and poly (dimethyl diallyl ammonium chloride) (PDDA), and the process assisted by the Hofmeister effect. A double conductive pathway hydrogel with types of PDDA and PANI polymers was formed simultaneously to provide excellent conductivity (1.217 S/m−1) for the hydrogel. With the increase in the concentration of PDDA from 0 to 16 wt%, the mechanical strength increased from 0.066 MPa to 0.34 MPa, and the modulus of elasticity and toughness increased by 684.9% and 748.8%, respectively. The hydrogel can be efficiently generated as a strain sensor material with excellent sensitivities of GF= 2.337 and S= 3.229%/KPa under tension and compression, respectively. The hydrogel could be used as an electronic skin and be used for the monitoring of even small strains in the skin caused by pulse beats. In addition, the hydrogel has excellent temperature sensitivity (1.575%/℃), frost resistance (−53.45 ℃), self-healing capability, and reusability.

What is Poly Allylamine Hydrochloride

Polyallylamine hydrochloride (CAS No. 71550-12-4) is a cationic polyelectrolyte prepared by the polymerization of allylamine. It can be used in combination with an anionic polyelectrolyte like poly(sodium styrene sulfonate) to form a layer-by-layer adsorbed film of negatively and positively charged polymers.

Impact of Polyallylamine Hydrochloride on Gene Expression and Karyotypic Stability of Multidrug Resistant Transformed Cells

The synthetic polymer, polyallylamine hydrochloride (PAA), is found in a variety of applications in biotechnology and medicine. It is used in gene and siRNA transfer, to form microcapsules for targeted drug delivery to damaged and tumor cells. Conventional chemotherapy often does not kill all cancer cells and leads to multidrug resistance (MDR). Until recently, studies of the effects of PAA on cells have mainly focused on their morphological and genetic characteristics immediately or several hours after exposure to the polymer. The properties of the cell progeny which survived the sublethal effects of PAA and resumed their proliferation, were not monitored. The present study demonstrated that treatment of immortalized Chinese hamster cells CHLV-79 RJK sensitive (RJK) and resistant (RJKEB) to ethidium bromide (EB) with cytotoxic doses of PAA, selected cells with increased karyotypic instability, were accompanied by changes in the expression of p53 genes c-fos, topo2-α, hsp90, hsc70. These changes did not contribute to the progression of MDR, accompanied by the increased sensitivity of these cells to the toxic effects of doxorubicin (DOX). Our results showed that PAA does not increase the oncogenic potential of immortalized cells and confirmed that it can be used for intracellular drug delivery for anticancer therapy.

Counterions in Poly(allylamine hydrochloride) and Poly(styrene sulfonate) Layer-by-Layer Films

The amount of counterions in layer-by-layer (LBL) films of poly(allylamine hydrochloride) (PAH) and poly(styrene sulfonate) (PSS) has been determined with X-ray photoelectron spectroscopy (XPS) for films prepared from solutions with various NaCl concentrations. Sodium and chloride counterions are present in LBL films produced from salt solutions, which are located at the surface and in the bulk of the films. The percentage of bulk counterions increases with the ionic strength of the polyelectrolyte before reaching a constant value. The bulk sodium/sulfur percentage ratios tend to 0.8 for samples washed with pure water and for samples washed with NaCl aqueous solutions, while the bulk chlorine/nitrogen percentage ratios tend to 0.5 for the same samples. The ratio between the percentages of polyelectrolyte ionic groups lies close to unity for all samples, indicating that counterions do not contribute to charge compensation in the polyelectrolyte during the adsorption process. The presence of counterions in LBL films is explained by Manning condensation near the polyelectrolyte ionic groups, leading to inter-polyelectrolyte ionic bondings via ionic networks. It is believed that condensation leads to the formation of NaCl crystallites in these LBL films, which was confirmed by X-ray diffraction measurements.

Layer-by-Layer Assembly of Poly(Allylamine Hydrochloride)/Polyurethane and Its Loading and Release Behavior for Methylene Orange

Here, layer-by-layer technique was used for sequential adsorption of oppositely charged polymer poly(allylamine hydrochloride) (PAH) and polyurethane (PU) through electrostatic interaction. 10 and 10.5 bilayer films were prepared separately, methylene orange (MO) was used as a model drug to evaluate the potential ability of this multilayer film used in drug delivery system. Experimental results showed the ability of loading and release of MO from the film was significantly influenced by pH and salt concentration, the loading rate of MO was faster and larger with increasing salt concentration or decreasing pH of MO solution, the release rate of MO was faster at higher salt concentration or in alkali solution. The result also indicated that the film had a good reversibility of loading and release. PAH/PU film could be a promising drug delivery system because of its biocompatibility, biodegradation and above properties.
