摘要：
The present invention relates to a new thermoplastic copolyether ester elastomer composition comprising a soft segment and a hard segment. The soft segment of the copolyether ester elastomer composition is derived from a random poly(oxyethylene-co-oxytetramethylene ether)glycol and the hard segment is composed of short chain polyester. The present invention also relates to a method for manufacturing the new copolyether ester elastomer composition, and products comprising same.
