Copolymerization
Copolymerization of two or more monomers during chain-growth polymerization is an effective way of altering the balance of properties of commercial polymers. Free-radical copolymerization of 20–35% of the relatively polar monomer acrylonitrile with the hydrocarbon styrene produces a transparent copolymer with better oil and grease resistance

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.

Copolymer - Definition, Types of Copolymerization, Examples
A copolymer is a polymer that is made up of two or more monomer species. Many commercially important polymers are copolymers. Examples include polyethylene-vinyl acetate (PEVA), nitrile rubber, and acrylonitrile butadiene styrene (ABS). The process in which a copolymer is formed from multiple species of monomers is known as copolymerization.

Polyacrylamide - Uk Leading Industrial Wastewater Treatment
Polyacrylamide is used to flocculate solids in a liquid. This process applies to water treatment, and processes like paper making and screen printing. Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being sub-categorised as a solution and a white emulsion polymer.

Polyacrylamide Handbook - SNF Holding
polyacrylamide emulsions and powders Handling of emulsions using pumps is simpler than powders and in many cases, in-line injection can be used, avoiding the need for an aging tank. Furthermore, dissolution times are much shorter and there are almost no solubility problems. Unlike powders, emulsions are complex multicomponent products which include

Copolymerization
This method is called gradient copolymerization. Statistical copolymers, on the other hand, are produced when the homo- and cross-propagation rates of the two monomers M 1 and M 2 are very similar or when the monomer feed ratio is kept constant throughout the polymerization.
