Development of Oxygene Enrichment Membrane of Polybutadine Containing Silyl

合成了由有机硅和双键组成的聚烷氧基硅基丁二烯，并在80~100ﾟC的湿度下固化。聚丁二烯分子之间的脱碱反应导致了聚丁二烯分子之间的交联，得到的橡胶聚合物可用于渗透成员渗透膜。与通常观察到的情况一样，膜的玻璃化转变温度随着交联度的增加而升高。用Henry模式吸附解释了CO_2、O_2、CH_4和N_2气体的吸附等温线。在聚烷氧基丁二烯中，聚异丙氧基丁二烯的氧渗透系数最大，为2.5×10~(-8)cm~(-3)STPcm/cm~2 SeccmHg，与硅橡胶膜相比，聚异丙氧基丁二烯具有较高的扩散系数，这主要是由于异丙氧基硅基丁二烯部分的交联形成的高扩散系数。

Polyalkoxysilylbutadiene which is composed of silicone and double bond is synthesized and cured under humidity at the temperature range 80-100ﾟC.The dealkolysis reaction resulted in crosslinking between polybutadiene molecules and rubbery polymer obtained was useful for permeation memb permeation membranes. The glass transition temperature of the membrane was increased with the degree of crosslinking as usually observed. Sorption isotherms of CO_2, O_2, CH_4, and N_2 gases were interpreted in terms of Henry mode sorption. Among polyalkoxysilylbutadienes polyisopropoxysilylbutadiene gave the highest O_2 permeability coefficient, eg., 2.5x10^<-8>cm^3STPcm/cm^2 SeccmHg and was available for highly permeable membrane compared to silicone rubber membrannes, which is mainly attributed to high diffusion coefficient formed by crosslinking of isopropoxysilylbutadiene moiety.
