Two-step synthesis of polyacrylamide/polyacrylate

Polyacrylamide (PAM) and polyacrylate (PAC) are typical superabsorbent polymers; however, the mechanical strength of single PAM or PAC is feeblish, which cannot meet the application requirement as a water treater [8, 9]. In this paper, to improve the mechanical strength of single PAM or PAC, a PAM/PAC with interpenetrating network (IPN

polyacrylamide

Polyacrylamide

From Wikipedia, the free encyclopedia Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1]

Spotlight on the Life Cycle of Acrylamide-Based Polymers

Polyacrylamide copolymers, either anionic or cationic, are potentially quickly converted to corresponding polyacrylate salts by deamination or hydrolysis. Therefore, biodegradation of related polyacrylic acid (or related salts) provides insights in polyacrylamide biodegradation and their fate.

Some of the most used AP are polyacrylamide, polyacrylic acid, polymethyl methacrylates, and polyacrylonitrile. Although no information for the production of all AP types is published, data for the most used AP is around 9 MT/year, which gives an idea of the amount of waste that can be generated after products¡¯ lifecycles.

The reduction in the negative zeta potential was found to be considerably greater in the presence of cationic polyacrylamide than anionic and amphoteric polyacrylamide, due to an increased adsorbed layer thickness of cationic polyacrylamide. 208 Amphoteric polymers exhibit both cationic and anionic behaviors, and their strength and a relative
