Preparation and properties of cationic polyacrylamide

Nano-silica/cationic polyacrylamide (S-CPAM) prepared by inverse emulsion polymerization of modified silica (C-SiO 2) as a hydrophobic component with acrylamide (AM), dimethyl diallyl ammonium chloride (DMDAAC) and Methacryloyloxyethyl trimethyl ammonium chloride (DMC).

Thermal decomposition behavior and mechanism study

12 Citations Explore all metrics Abstract The thermal decomposition behavior of polyacrylamide poly (methacryloyloxyethyl trimethylammonium chloride-acrylamide) (P (DMC-AM)) was studied by means of TG and DSC under nitrogen atmosphere at temperature range of 323.15¨C823.15 K. The effect of cationicity on thermal stability was discussed.

Research on a new cationic polyacrylamide (CPAM)

The cationic monomers on these microblock segments can be polymerized to form a CPAMD with a new cationic microblock structure. In addition, microwave has mechanical effects such as oscillation, emulsification, and diffusion, which can accelerate the heat and mass transfer process of the reaction system, thus accelerating the reaction rate (Wiesbrock et al. 2004; Hoogenboom and Schubert 2007

Preparation of novel amphoteric polyacrylamide and its

A novel amphoteric polyacrylamide (PDAA) was prepared by inverse emulsion polymerization. The influence of its cationic degree and molecular weight on retention property was discussed. Then, the chemical structure and micromorphology of the obtained PDAA were characterized by Fourier infrared spectrum (FTIR), NMR hydrogen spectrum ( 1 H NMR), gel permeation chromatography (GPC), and scanning
