Some Aspects of the Properties and Degradation of

Polyacrylamide gels are made by chemical polymerization of a mixture of acrylamide and bisacrylamide (a cross-linker) in the presence of a catalyst and an initiator of the polymerization reaction. The porosity of the gel is determined by the relative concentration of acrylamide to cross-linker and by the total percentage of monomers.

(Mannsville Chemical Products Corp., 1985; Habermann, 1991; Smith & Oehme, 1991). Catalytic hydration of acrylonitrile with copper metal or Raney copper catalyst was introduced in 1971. ln this process, a solution of acrylonitrile in water is passed over a fixed bed of catalyst at 85°C, and the acrylonitrile is converted directly to acrylamide.

Types of catalysts (article) | Kinetics | Khan Academy

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions.
