摘要
核磁共振 (1 H- NMR)、透射电镜 (TEM)和粘度测定法的结果表明两亲接枝共聚物聚甲基丙烯酸甲酯接枝聚氧乙烯 (PMMA- g- PEO)在甲苯中可形成胶束 ,PMMA- g- PEO的浓度和体系的温度决定着胶束的大小及 CMC值。将 PMMA- g- PEO应用于丙烯酰胺的反相乳液聚合 ,结果表明 ,可形成稳定的乳液。 PMMA- g- PEO用量越大 ,丙烯酰胺的聚合速率越快 。
It is characterized by 1H NMR, TEM and viscometry measurement that micelles can be formed for amphiphilic graft copolymer poly(methyl acrylate) g poly(ethylene oxide)(PMMA g PEO)in toluene. The concentration of PMMA g PEO and temperature of system determine the conformation of micelles and CMC value. When PMMA g PEO is used as emulsifier in acrylamide inverse emulsion polymerization, the stable inverse emulsion can be formed, with a increase in concentration, the rate of polymerization increase, the size of polymeric particles and stabilization also increase.
