Synthesis of Semi-enclosed Solution Polymerization Method of Polyacrylamide

With redox initiation system and semi-enclosed solution polymerization method,preparaed methylacryloxyethyltrimethyl ammonium chloride-dimethyl diallyl ammonium chloride-acrylamide(DMC-DMDAAC-AM copolymer)cationic flocculant.the polymer was structure characterized by infrared spectroscopy and nuclear magnetic.Studied the effects of the monomer ratio,the cationic mole fraction,contents of the initiator and the ratio promoter on product performance;studied effective characteristics of the viscosity and dissolved performance.Under the same conditions of the monomer ratio,improved the cationic degree and flocculation performance.The results showed that the best response mole fraction was:AM:16.72%,DMC:12.84%,DMDAAC:13.56%,deionized water:53.64%,EDTA:0.003 12%,AIBA:0.044 22%,APS:0.001 82%,SFS:0.001 76%.
