Polymer composition and core-shell elastomer used therefor. |
摘要 |
A polymer composition comprising [A] a polymer selected from a copolymer of alpha -olefin having at least 2 carbon atoms and a specific cyclic olefin, a ring-opening polymer of said specific cyclic olefin and a hydroganted, ring-opening polymer thereof and [B] a core-shell elastomer containing 40 to 85 parts of weight of a core component which comprises a styrene-butadiene copolymer and 15 to 60 parts by weight of a shell component which comprises a copolymer of an acrylate or methacrylate having a specific cyclic structure, a monovinyl aromatic monomer, other monovinyl monomer and a plyfunctional monomer. This polymer composition is excellent in transparency and impact resistance. |
