  • Butenediol-based Polyester Elastomer and Method for Preparing Same
    Publication number: 20220363821
    Abstract: The present disclosure discloses a butenediol-based polyester elastomer and a method for preparing same. In the present disclosure, 1,4-butenediol containing high-stability double-bond is used to replace itaconic acid, and a series of butenediol-based polyester elastomers with high molecular weight and narrow distribution are synthesized, which have high relative molecular weight and narrow relative molecular weight distribution. The crosslinking in subsequent processing is more controllable, and the dosage of a vulcanizing agent is equivalent to that of traditional rubber.
