UV-Initiated Graft Copolymerization of Cationic Chitosan
UV-Initiated Graft Copolymerization of Cationic Chitosan-Based Flocculants for Treatment of Zinc Phosphate-Contaminated Wastewater | Industrial & Engineering Chemistry Research. 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).
A ternary cationic polyacrylamide (CPAM) with the hydrophobic characteristic was prepared through ultraviolet- (UV-) initiated polymerization technique for the estrone (E1) environmental estrogen separation and removal. The monomers of acrylamide (AM), acryloyloxyethyl-trimethyl ammonium chloride (DAC), and acryloyloxyethyl dimethylbenzyl ammonium chloride (AODBAC) were used to synthesize the

UV-initiated polymerization is also easy to operate and environmentally friendly , . As a new polymerization technique used to synthesize P(AM–DAC–BA), UV-initiated polymerization is good for overcoming problems associated with traditional polymerization methods and for surface modification , . The specific surface area can be remarkably increased by UV-initiated polymerization, which can strengthen the adsorption-bridging ability of P(AM–DAC–BA) in textile sewage sludge dewatering.

In this study, a new cationic polyacrylamide (CPAM) was successfully synthesized through UV-H 2 O 2-initiated polymerization technique using acryloyloxyethyl trimethyl ammonium chloride (DAC) and acrylamide (AM) as monomers, and applied to sludge dewatering experiments.Parameters affecting the molecular weight and conversion of the polymers, including total monomer concentration, monomer
- What is the molecular weight of Pam?
- The molecular weight (MW) of commercial PAM ranges from 10 5 to >10 7 Da. High MW PAM (>10 6 Da) has a wider range of applications due to its high viscosity, drag reduction capabilities, and water retention characteristics. 6, 7, 8 PAM is widely used in environmental systems including: 1. 2. 3.
- What is the association between Pam and 10 million molecular weight?
- The association of PAM with 10 million molecular weight in solution shows a loose network structure of micro-gels with a size of about several hundred nanometers.
- Is polyacrylamide a water soluble polymer?
- Polyacrylamide (PAM) is a synthetic water-soluble polymer, which is also commonly applied as a viscosity modifier in cementitious materials [ 11, 12 ]. Owing to its high molecular weight (up to 30 million) as well as the -COOH and -CONH 2 groups present in its structure, PAM confers thickening properties [ , , , , ].
- Can high molecular weight Pam be used for degradation?
- This paper provides a short review of current applications of high molecular weight PAM, including the potential for PAM degradation by chemical, mechanical, thermal, photolytic, and biological processes.
