Abstract
A process for the preparation of a segmented thermoplastic copolyester elastomer comprising a multiplicity of periodic intralinear long-chain ester units derived from a dicarboxylic acid or its ester-forming equivalents and a long-chain glycol or its ester-forming equivalents and short-chain ester units derived from a dicarboxylic acid or its ester-forming equivalents and a low-molecular-weight diol or its ester-forming equivalents, said head-to-tail ester units being attached through ester linkages and prepared by reaction of : (a) one or more dicarboxylic acids with a molecular weight less than 300 or their ester-forming equivalents, (B) one or more low-molecular-weight diols less than about 250 or their ester-forming equivalents, and (C) one or plus poly (alkylene oxide) glycols with a molecular weight of approximately 400-4000 and a carbon to oxygen ratio between and approximately 2.0 and 4.3 or their ester-forming equivalents, the process of which is characterized in that the preparation is carried out in the presence of a stabilizing amount of 1,3,5-tri- (3,5-di-tert-butyl- 4-hydroxy-hydrocinamoyl) hexahydro-s-triazine.
