摘要: 80年代才研制的聚1-三甲硅基丙炔(PTMSP)的Tg高于200℃,而它在室温的气体透过性呈橡胶态聚合物的特性,透氧和透醇速率极高,Po2达5×103Barrer,是一代新型富氧膜材料。但TMSP制备和聚合难度大。目前尚只有日、美[1-5]等国取得一些进展,他们采用丁基铝法合成了TMSP,但此法安全防护难、成本高,不适合土业放大。

Abstract: Po1y[1-(trimethy1si1yl)-1-propyne](PTMSP) of higher molecular weight was synthesized by cationic polymerization in solution. It has a structurc of [-C(Me)=C(SiMe3)-). It is an amorphous,soluble solid.The permeability to oxygen and selecfivity of O2/N2 of PTMSP membrane are reported after various modification.
