Stabilized thermoplastic elastomer compositions |
摘要 |
Segmented thermoplastic copolyester elastomers containing recurring polymeric long chain ester units derived from phthalic acids and long chain glycols and short chain ester units derived from phthalic acids and 1,4-butanediol or 1,4-butenediol. The elastomers also contain polyvinylpyrrolidone and preferably also contain small amounts of guanidine stabilizer, phosphorus stabilizer and diphenylamine.
