N-(α-甲基-丁酯基)马来酰亚胺的微乳液聚合

Microemulsion Polymerization of N - (α - methyl - butyoxl)maleimide

以上二烷基硫酸钠和正戊醇为复合乳化剂,配制了N-(α-甲基-丁酯基)马来酰亚胺的微乳液.用过硫酸钾引发该体系聚合,得到了既定的聚合物,考察了聚合速率随转化率的变化以及温度和引发剂浓度对聚合速率的影响.引发剂浓度增大,聚合反应速率提高,对应的斜率为0.5.根据温度对聚合的影响可得E_(R_p)约为92.8mol/L.并用PERKIN-ELMER FTIR-1710红外光谱仪对聚合物进行了检测.

The microemulsion containing N - (a - methyl- butyoxl) maleimide was prepared with sodium dodecyl sulfate(SDS) as emulsifier and potassium persulfate (KPS) as the initiator. The change of polymerization rate with conversion was recorded. At the same time, the polymer was characterized by h - NMR.
