反相微乳液法合成两性离子聚丙烯酰胺

摘要

以丙烯酰胺、丙烯酸和甲基丙烯酰氧乙基三甲基氯化铵为主原料，用反相微乳液聚合技术合成两性聚丙烯酰胺。研究了合成高分子量产物的工艺条件，结果表明，当引发剂用量为0．28％，单体浓度为48％，乳化剂用量为16．8％，油水质量比为1：1．2，反应温度为20℃时，所得的产物分子量最高。%ith acrylamide ,acrylic acidfor and methacrylatoethyle trimethyl ammonium chloride as the main raw material ,amphoteric polyacryl -amide is synthesized by inverse microemulsion poly -meriza-tion .The conditions of highe molecular weigh product were studied ,the results show that :when initia-tor dosage is 0 .28% ,monomer dosage is 48% ,emulsifier dosage is 16 .8% ,oil-water mass ratio is 1 :1 .2 ,reaction temperature is 20℃ ,we got the highe molecular weight of the product .
