摘要
采用COBF[bis(aqua)bis(difluorobory1)dimethyl yoximato)cobalt(Ⅱ)]为催化剂,AIBN为引发剂,以甲基丙烯酸丁酯、2-丙烯酰胺基-2-甲基-丙磺酸,甲基丙烯酸-β-2-羟乙酯等合成了带有磺酸基团和羟基的高分子表面活性剂。运用红外光谱IR和1HNMR对合成的产物进行了结构表征,测定了聚合物的表面张力、临界胶束浓度,结果表明,合成的聚合物具有良好的表面活性。把得到的聚合物用于乳液聚合,通过动态光散射和原子力显微镜测定乳液的粒径、观察形貌,乳胶粒粒径分布均匀。
Using bis （aqua）bis （difluoroboryl）dimethyl yoximato cobalt（ II ） as the chain transfer catalyst. AIBN as initiator, using BMA,AMPS ,HEMA as raw materials, New kinds of polymeric surfactants with sulfonic group and hydroxy were synthesized by catalytic chain transfer polymerization. The polymer was characteristiced by FT-IR and 1HNMR, mensureated the surface tension and critical micelle concentration （CMC）, the result showed that synthesized polymer had good surface-active, the synthesized polymer was used in emulsion polymerization, steady system was gained, its size distribution was uniformity.
