In order to develop the conditions for preparing polymers with different molecular masses, the authors continued their investigation of TMSP (1-(trimethylsilyl)-1-propyne) polymerization catalyzed by TaCl{sub 5} and TaCl{sub 5}/BuLi at various ratios of VTMS (regulator of molecular mass of the polymer) : catalyst. They also studied the effect of the structure of silahydrocarbon on the process of TMSP polymerization. To this end, they carried out polymerization of TMSP in the presence of additives of vinylphenyldimethylsilane and vinylallyldimethylsilane. The conditions of experiments and the results obtained are shown. The method for controlling the molecular mass of PTMSP makes it possible to prepare PTMSP suitable for manufacture of both flat membranes and hollow fibers. The paper also describes the experimental study of PTMSP gas permeability, gas sorption in PTMSP, and a computer program for the prediction of all gas permeability parameters of polymers.
