THERMOPLASTIC COPOLYESTER COMPOSITIONS MODIFIED WITH EPOXIDECOMPOUNDS

摘要

Copolyether ester elastomers are provided which contain epoxide compounds. T he compositions show improved bloom resistance in the presence of diamines with minimum increase in melt viscosity. Also disclosed are methods to improve appearance and eliminate bloom from finished products comprising thermoplast ic copolyesters by lowering the level of acid terminated oligomers in the thermoplastic copolyesters with epoxide compounds.
