文摘The emulsion of cationic polyacrylamide was prepared by a soap-free polymerization,using water as media,the oligomer that prepared by myself as emulsifier and stabilizer,(NH4)2S2O8 as initiator.The effect of the amount of isopropanol,oligomer and the ratio of DMC/AM on the molecular weight of cationic polyacrylamide were all studied.The best amount of isopropanol,oligomer are 25%,20% of the total monomer and the ratio of DMC/AM is 3/7.
