摘要
在Ｌ－谷氨酸－ｒ－甲酯（ＭＬＧ）与聚二甲基硅氧烷（ＰＤＭＳ）合成ＰＭＬＧ／ＰＤＭＳＡ－Ｂ型嵌段共聚膜［１］的基础上．进一步成功合成了Ａ－Ｂ－Ａ型嵌段膜。用ＩＲ、Ｘ－Ｒａｒ等测试方法确认了不同共聚组成ＭＳiＭ膜的相区结构及特征．结果表明：Ａ、Ｂ组份不仅存在不同的微相结构，而且在其界面区域的ＰＭＬＧ（Ａ组份）部分还产生了无规线团结构。
A-B-A type block copolymer(MSiM) membranes consisting of Poly (7-methylL-glutamate) (PMLG, A component ) and polydimethylsiloxane (PDMS, B component)have been prepared. Phase separastion between a-helical PMLG and PDMS components hasoccurred in MSiM membranes, at the interface between the two phases, random- coil sturture was induced in PMLG component.
