| 摘 要： | 以过硫酸钾（KPS）为引发剂、以十二烷基硫酸钠（SDS）和正戊醇（PTL）为复合乳化剂，对N-马来酰基-L-氨基丙酸（AMI）和苯乙烯（St）进行了微乳液共聚合实验并制得了具有光学活性共聚物．考察了单体配比、引发剂浓度、温度对反应速率（R，）的影响．用元素分析法确定了共聚物内氮含量与单体组成比之间的关系，进而计算出两单体的竞聚率，并计算出相应的Q、e值：r1=0．05，r2=0．10，Q1=1．59，e1=1．50．计算了共聚合反应活化能Ea值：Ea=82．86kJ／mol．讨论了共聚物组成及二元序列、平均序列长度、温度对共聚物旋光度的影响．

| Abstract: | Chiral N-maleoyl-L-alanine(AMI) and styrene(St) were copolymerized in the oil-water microemulsion by using potassium persulfate(KPS) as initiator,sodium dodecyl sulfate(SDS) as anionic emulsifier,and pentanol as consurfactant.The resulting polymers are optically active.The monomer reactivity ratios(r_1,r_2),Alfrey-Price Q,and e values are calculated, which are r_1=0.05,r_2=0.10,Q_1=1.59,and e_1=1.50,respectively.The effects of initiator concentration,molar fraction of monomer in feed and reaction temperature on the polymerization rate(R_p) have been investigated.The overall energy of activation(E_a) is 82.86 kJ/mol. |
