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.

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 ℃的湿度下固化。脱醇反应导致聚丁二烯分子与橡胶聚合物交联，所得橡胶聚合物可用于渗透构件渗透膜。如通常观察到的，膜的玻璃化转变温度随着交联度而增加。CO_2、O_2、CH_4和N_2气体的吸附等温线符合亨利吸附模式。在聚烷氧基硅基丁二烯中，聚异丙氧基硅基丁二烯的透氧系数最高，2.5 × 10 ^<-8>cm^3STPcm/cm^2 SeccmHg，与硅橡胶膜相比，可用于高渗透膜，这主要归因于异丙氧基硅基丁二烯部分交联形成的高扩散系数。
