Abstract
The structure and phase transitions of block copolymers of PBT and PEO having different composition were investigated by DSC, SAXS, and WAXS. Two different glass transitions and two melting points were observed. The increase of the integral SAXS intensity with temperature was much smaller than in the case of homopolymers, which is explained by a broad melting range. The long period strongly increases with temperature, which is attributed to growth of domains.Keywords
