【Abstract】 The synthesis of Dimethyldiallylammonium Chloride was made from Chloropropene by quaterisation,and then the copolymer of DMDAAC and AA and AM was obtained which was used widely.The optium synthetic condition were determined.At a molar ratio of chloropropene to dimethylamine to sodiun hydroxide 2.2∶1.0∶1.0,dropping temperature 10～30℃ for 3h and then constant temperature 50℃ (boiling temperature of chloropropene) for 4h, yield of DMDAAC was 94%. At a molar ratio of DMDAAC to AA and AM 1∶2.6, AA to AM 1∶3.5, concetration of catalyst 0.5%,at a molar ratio of oxidize agent to reducing agent 1∶0.6,reacting at 60℃ for 3h first, the post polymerization time 3.4h. The influence factors were studied and the synthetic conditions were determinded.The copolymer was used for shampoo and it shows that P(DMDAAC/AA/AM)is superior than P(DMDAAC/AM), especially its compatibility.更多还原
