Abstract: Polyether-ester thermoplastic elastomer, such as polyethylene glycol terephthalate-butylene terephthalate copolymer (PEGT/PBT) was synthesized by melt polycondensation from polyethylene glycol, butanediol and dimethyl terephthalate with Ti(OBu) 4 as catalyst. The copolymer was characterized by means of GPC?FTIR? 1HNMR and 13 CNMR. The results show that the product consists with what we have designed.

Key words: PEGT/PBT copolymer, thermoplastic elastomer, poly(ether-ester) segmented copolymers
