Abstract
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.
