A thermoplastic copolyester elastomer which comprises dicarboxylic acid component mainly composed of terephthalic and phthalic acids, wherein the molar ratio of terephthalic acid to phthalic acid is from about 80/20 to 35/65, and diol component mainly composed of 1,4-butanediol. The elastomer has excellent thermal stability and weatherability and can be improved in the elastomeric properties by orientation of polymer molecule before crystallization.
