  • Elastomer - Modified thermoplastic olefin polymer compositions
    Patent number: 5585441
    Abstract: A thermoplastic composition comprising a crystalline propylene polymer and as a modifying elastomer, a hydrogenated butadiene polymer which is either an essentially linear hydrogenated butadiene homopolymer or a star-branched polymer, the arms of which are an essentially linear hydrogenated butadiene homopolymer, such hydrogenated butadiene polymer containing from about 20 to about 90% of polymerized butadiene units with the 1,2-microstructure and having a polydispersity index (P.I.) of about 1.01 to 1.50. The compositions have a superior combination of processing and mechanical properties such as flexural strength, impact resistance, and melt flow.
