Method for producing high molecular weight polyacrylamide type resins
摘要:
High molecular weight acrylamide polymers useful as flocculants are obtained by copolymerizing acrylamide with a monovinyl monomer in a mixture of water and acetone in the presence of a redox type catalyst comprising a persulfate, an aliphatic amine and at least one Lewis acid selected from the group consisting of chlorides and bromides of aluminum, antimony, lithium and zinc.
