Abstract
A special affinity of poly(1-(trimethylsilyl)-1-propyne), PMSP, toward other materials has been investigated. The oxygen permeability of PMSP thin membranes decreased with time, depending on the environmental conditions in which the membrane was kept. It was observed that PMSP has high gas solubility coefficients compared with other polymers from sorption measurements. From the results the deterioration of the membrane was explained essentially in terms of absorbance of some additives to PMSP membrane having a certain morphology. In composite membranes produced from such mixtures a generation of an interface layer between PMSP and an additive was demonstrated using a bilayered model membrane consisting of PMSP and porous polysulphone membrane. A three-layered composite membrane (silicone-copolymer/PMSP/polysulphone) designed on the basis of the results was shown to have high oxygen permeability, high separation factor and high durability.
