Copolyether ester elastomers are provided which contain epoxide compounds. The 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 thermoplastic copolyesters by lowering the level of acid terminated oligomers in the thermoplastic copolyesters with epoxide compounds.
