a cationic polyacrylamide polymer distributors of Poland
Recently, more attentions have been paid to natural polymer-based flocculants in water treatment, since they are believed to be low-cost, nontoxic, and environmentally friendly materials. In this work, strong cationic chitosan-based graft copolymer flocculants (3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CTA) modified chitosan-graft-polyacrylamide, denoted as chitosan-CTA-g-PAM) have
In this study, acrylamide and [2-(acryloyloxy)ethyl] trimethylammonium chloride were grafted onto CS by UV initiation to obtain an environmentally friendly graft copolymer, CS-g-poly(acrylamide-acryloyloxyethyl) trimethylammonium chloride (CS-g-PAD). Poly(acrylamide-acryloyloxyethyl) trimethylammonium chloride was named as PAD. Nuclear magnetic resonance hydrogen spectroscopy (1H NMR), X-ray
