Copolymerization
Different from other reported catalysts, which bring about the copolymerization of CO 2 and epoxide only under the high CO 2 pressure (> 6.8 atm) 4, (TPP)MnOAc (1) afforded polycarbonate even under the CO 2 atmosphere of 1 atm, although the reaction proceeded more slowly than that under 50 atm of CO 2 pressure ([CHO] 0 /[1] 0 = 500).

Polyacrylamide
Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.

Polyacrylamide
Polyacrylamide (PAAM) forms soft, cationic nondegradable hydrogels consisting of entangled polymer chains tethered to one another via cross-linkers [175]. Its hydrophilic nature results in a high capacity for swelling and tendency for cell (bacterial and mammalian) adhesion and migration, granuloma formation, and fibrosis in vivo [152,153,176].

Copolymer
Graft copolymers are a special type of branched copolymer in which the side chains are structurally distinct from the main chain. Typically the main chain is formed from one type of monomer (A) and branches are formed from another monomer (B), or else the side-chains have constitutional or configurational features that differ from those in the main chain.

Acrylamide - Chemical Economics Handbook (CEH) | IHS Markit
EOR will continue to be the largest segment in the Chinese market, followed by water treatment. In Western Europe and the United States, large quantities of acrylamide are believed to be consumed in the manufacture of polyacrylamide, which is devoted to the export market. For this volume, no breakdown by end-use market is available.
