## Abstract A new type poly(ether–ester) based on poly(trimethylene terephthalate) as rigid segments and poly(ethylene oxide terephthalate) as soft segments was synthesized and its aging behavior were investigated. Different from other polymer, the segmented block copolymers exhibited a unique agin

The block copolymers of poly(butylene succinate) (PBS) and poly(butylene terephthalate) (PBT) were synthesized by melt processing for different times. The sequence distribution, thermal properties, and crystallization behavior were investigated over a wide range of compositions. For PBS/PBT block co
## Abstract **Summary:** Analysis was made of the crystallization of the PET blocks in PET/PC copolymers as a function of the block length, varying from $\overline M \_{\rm n}$ = 5300 to 17100 g · mol^−1^ (__X__~n PET~ = 28–89, PET monomeric sequences). Analysis was also made of a series of PET hom
