## Abstract Segmented block copolymers comprised of flexible PEO segments and monodisperse crystallizable bisestertetraamide segments have been synthesized. The influence of the terephthalic units in the soft phase on the transitions and the thermal mechanical and elastic properties are studied. Th

## 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
## Abstract A new route of synthesis of block copolymers was investigated. It involves the polymerization of a sideβchain liquidβcrystalline acrylate and poly(propylene glycol), modified by an esterification reaction with mercaptoacetic acid used as macrotransfer agent, in the presence of 2,2β²βazoi
