Polymer blends containing polymer of beta -hydroxybutyric acid and chlorine or nitrile group containing polymer |
摘要 |
Polymer blends containing (i) 0.2-95% by weight of a high molecular weight beta -hydroxybutyric acid homo- or copolymer and (ii) a polymer containing at least 25% by weight of chlorine or nitrile groups, such as chlorinated polyethylene, polyvinyl chloride, or a high acrylonitrile resin. In small quantities the beta -hydroxybutyric acid polymer acts as a processing aid for the chlorine or nitrile containing polymer. In larger quantities the properties of the beta -hydroxybutyric acid polymer or the chlorine or nitrile containing polymer are improved.
