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.

Abstract: A solution polymerized styrene-butadiene rubber-polyurethane elastomer material and a preparation method thereof are provided. The elastomer material is prepared by performing cast molding on a soft segment and a hard segment in a mass ratio of 100:(20-50); the soft segment includes hydroxyl-terminated solution polymerized styrene-butadiene moiety rubber prepared by an anionic polymerization; the hard segment comprises isocyanate, a small-molecule polyol chain extender and a cross-linking agent; and the soft segment has a molecular weight of 1000-8000 and a glass-transition temperature of ?20° C. to ?30° C.
