高分子富氧膜研究Ⅱ.二甲基硅氧烷齐聚物与对羟基苯乙烯齐聚物交联共聚物的合成与表征
摘要:
研究了α,ω-双二甲胺基聚二甲基硅氧烷与对羧基苯乙烯齐聚物(pHS)之间的溶液共缩聚反应,制得了高分子量的有机硅交联聚物。用多种方法测定了交联共聚物的结构和性能,发现它存在微观相分离结构,在一定的有机硅含量范围内均为低晶物,共聚物大分子链上尚保留可供进一步化学修饰的官能团,且具有优异的成膜工艺性,较好的氧氮气体选择透过性。

STUDY ON OXYGEN ENRICHMENT POLYMERIC MEMBRANES Ⅱ.SYNTHESIS AND CHARACTERIZATION OF CROSSLINKED COPOLYMER FROM OLIGOMER CONDENSATION OF α.ω-BIS-(DIMETHYLAMINO) DIMETHYLSILOXANE WITH HYDROXYSTYRENE
Abstract:
The solution crosslinking condensation reaction of α,ω-bis-(dimetylamino) dimethylsiloxane oligomer with hydroxystyrene oligomer was studied. The structure and properties of the crosslinked copolymers obtained were examined by IR, DSC, WAXD, polarizing microscopy, viscosity and GPS(gas permsetectivity) etc..It was found that the crosslinked copolymers which containing certain amount of organosiloxane have two mierophases and low crystallinity showed a better permselectivity for oxygen and nitrogen. Moreover, some hydroxy-groups are remained in the macromolecule backbone of the end copolymers and they may be used for further chemical modification.
