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 small amounts of a guanidine stabilizer and small amounts of phosphorus stabilizer and diphenylamine.
