摘要：
A series of novel poly(trimethylene tereplitlialate)-block-poly(tetramethylene oxide) (PTT-PTMO) segmented block copolymers were synthesised by transesterification in the melt of dimethyl terephthalate, 1,3-propanediol and poly(tetramethylene oxide) glycol (PTMO, 1000 g/mol). A range of multiblock copolymers were synthesized, with flexible PTMO segments contents varying from 20 to 80 wt%. The novel poly(ether-block-ester)s were characterized by using viscometry, hardness measurements, differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), and tensile properties.
