## Abstract This article discusses the rate of water vapor transmission (WVT) through monolithic films of segmented block copolymers based on poly(ethylene oxide) (PEO) and monodisperse crystallisable tetraβamide segments. The polyether phase consisted of hydrophilic PEO or mixtures of PEO and hydr
Block copolymers of polysulfone-poly(alky1ene oxide)-poly(dimethylsi1oxane) have been prepared by the addition of preformed a,w-bis(hydrogensily1) poly(dimethylsi1oxane) oligomers to allyl end-capped poly(alky1ene oxide)-polysulfone. The hydrosilylation reaction, catalyzed by platinum, was employed
