Polyacrylamide - Wikipedia

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] Physicochemical properties [ edit] Polyacrylamide is a polyolefin.

Polyacrylamide - an overview | ScienceDirect Topics

Polyacrylamides (PAMs) are relatively inexpensive polymers that are easily formulated to high molecular weights on the order of several million g/mol. PAM was first used in the paper industry in the mid-1950s.

Polyacrylamide | Formula, Properties & Application

Structure and Synthesis. Polyacrylamide is a linear polymer chain with recurring acrylamide subunits. Its formula can be expressed as (C 3 H 5 NO) n, illustrating the repeating nature of its constituent monomers. The synthesis of polyacrylamide typically involves the polymerization of acrylamide (C 3 H 5 NO) monomers, often through a free

Effects of physicochemical properties of polyacrylamide (PAA

Chemistry of polyacrylamide and its polymerization Polyacrylamide [IUPAC poly(2-propenamide), hereafter PAM] is a polymer (¨CCH 2 CHCONH 2 ¨C) formed from acrylamide subunits. Polyacrylamide with only acrylamide monomers is nonionic; other monomers such as acrylate or 2-acrylamido-2-methylpropane sulfonate (AMPS) can be copolymerized at

The New Approach to the Preparation of Polyacrylamide-Based

The structure of the synthesized polyacrylamide was characterized by XRD, 1 H NMR, and 13 C NMR spectroscopy. It was shown that 1,3-dimethylimidazolium (phosphonooxy-)oligosulphanide is able to initiate radical polymerization under drying aqueous solutions of acrylamide, even at room temperature.
