高分子量速溶型聚丙烯酰胺的合成

Synthesis of High Molecule and Fast Solutixed Polyacrylamid

研究了采用Ｓｐａｎ－ＯＰ复合乳化剂和Ｋ２Ｓ２Ｏ８水溶液引发剂进行丙烯酰胺的反相微乳液聚合，通过正交设计实验，对获得稳定微乳液体系的条件进行了优化选择，分析了影响聚丙烯酰胺分子量的因素，探讨了聚丙烯酰胺的合成方法及其溶解性，试验合成了高分子量、速溶、粉末状聚丙烯酰胺产品。

Using Span OP composite emulsifier and K 2S 2O 8 initiator,the inverse microemulsion polymerization of acrylamide (AM) was studied.The optimal forming conditions of the inverse microemulsion system were selected from cross design,the factors of influence on its molecule were discussed and the process to obtain fast solutized polymer was found.The synthesis product was high molecule,fast solutized and powdered ones.
