Polyacrylamide - Wikipedia

[1] Copolymers and modified polymers Linear polyacrylamide is a water-soluble polymer. Other polar solvents include DMSO and various alcohols. Cross-linking can be introduced using N,N-methylenebisacrylamide. Some crosslinked materials are swellable but not soluble, i.e., they are hydrogels .

Sep 7, 2018 · The term “polyacrylamide” is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which...

Acrylamide is a chemical used primarily to make substances called polyacrylamide and acrylamide copolymers. Polyacrylamide and acrylamide copolymers are used in many industrial processes, such as the production of paper, dyes, and plastics, and in the treatment of drinking water and wastewater, including sewage.

Polyacrylamide Polymer - an overview | ScienceDirect Topics

Acrylamide is a common monomer for various copolymers as well as in regular polyacrylamide gels. For example, copolymers of acrylamide and allyl gluconic lactobionic acid can be used to self-coat the capillary wall, allowing DNA fragments to be efficiently separated in an uncoated capillary [54].

Polyacrylamide - an overview | ScienceDirect Topics

Gold nanoparticles were encapsulated in a hydrogel made of polymerized NIPAM and acrylic acid units. The resulted copolymer showed both pH (PAA component) and thermo (PNIPAM component) responsive properties. These properties have the potential to be manipulated for the use in photothermally-activated drug delivery vehicles [53].
