Research on a new cationic polyacrylamide (CPAM) with a cationic

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 ...

synthesis, characterization, and flocculation properties of branched

Synthesis, Characterization, and Flocculation Properties of Branched

A water soluble branched cationic polyacrylamide (BCPAM) was synthesized using solution polymerization. The polymerization was initiated using potassium diperiodatocuprate, K ] (Cu (III)), initiating the self-condensing vinyl copolymerization of acrylamide and acryloxyethyltrimethyl ammonium chloride (DAC) monomer.

Polyelectrolyte polymers¡ªTypes, forms, and function

The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers [80] .

Cationic polyacrylamide copolymers (PAMs): environmental half life

Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.

Recent Achievements in Polymer Bio-Based Flocculants for Water

An example is work by Zhou and Framks , where three cationic polymers (homopolymer of diallyldimehylammonium chloride and its two copolymers with acrylamide) of different molecular weights (1.1¨C3.0 ¡Á 10 5 g/mol) and charge density (CD) (10%, 40%, and 100%) were used as flocculants for silica aggregates. They conducted experiments in apparatus constructed for aggregation (mini-thickener) and ...

Controlled Polymerization of Acrylamide via One-Pot and One-Step

The cationic polyacrylamide, Organopol 5415, with very high mol. wt. and low charge d. had the highest flocculation efficiency for paper mill wastewater treatment. It achieved 95% turbidity redn., 98% TSS removal, 93% COD redn., and sludge vol. index (SVI) of 14 mL/g at an optimum dose of 5 mg/L. SVI values

Spotlight on the Life Cycle of Acrylamide-Based Polymers Supporting

From a chemical point of view, one of the most interesting processes to obtain improved degradable polyacrylamide or hydro soluble polymers is the initiation of polymerization with Ce 4+ ions using an alcohol as reducing agent. By selecting monomer bearing alpha alcohol function, biodegradation may be observed (hybrid polymers of biodegradable ...
