To improve the low temperature elastic recovery and tensile properties of the traditional poly(ether-ester), a series of randomly branched poly(ether-ester)s consisting of poly(butylene isophthalate) as hard segment, poly(tetramethylene glycol) and poly(ethylene glycol) as mixed soft segment, and trimethylolpropane as trifunctional monomer were synthesized. The structure and composition of the samples...
A series of aliphatic-aromatic copolyesters derived from diverse ratios of diols (ethylene glycol, 1,4-butanediol and 1,6-hexanediol) and diacids (succinic acid and dimethyl terephthalate) have been synthesized by melt polymerization. The optimal thermal and mechanical properties as well as biodegradability of prepared copolyesters have been investigated by controlling the content of diols and diacids...
