Synthesis of super high molecular weight copolymer of AM/AA/AMPS and its salt by new initiators in inverses suspension polymerization

摘要

Polyacrylamide and its copolymers are important products in the water-soluble polymer industry. They are commonly used in oil exploit, water treatment, paper making and so on. Especially in oil exploit, there has been an increasing interesting in them. However they have some weakness in the capacity of heat-resistant and salt-resistant. It was studied that the copolymer of acrylamide (AM) and acrylamidomethylpropane sulfonic acid (AMPS) can solve these problems.
