    摘要： There are disclosed novel, solid, elastomeric block copolymers having excellent oxidative and thermal stability, wherein the terminal blocks are each a polymer (D polymer) of at least one conjugated diene D, which is a hydrocarbon containing a 1,3-conjugated diene structure wherein the 2 and 3 carbon atoms are each additionally bonded to a hydrocarbyl side group, e.g., 2,3-dimethyl-1,3-butadiene, with a preponderance of polymerized D units being 1,4 units; and at least one interior block is a hydrogenated polymer (I polymer) of at least one conjugated diene I which is a hydrocarbon containing a 1,3-conjugated diene structure wherein one of the 2- and 3-carbon atoms is additionally bonded to a hydrocarbyl side group and the other is additionally bonded to a hydrogen atom, e.g. isoprene. The block copolymers may be prepared by selectively hydrogenating substantially all the I polymer units of a precursor block copolymer with a sufficient number of D units in the D polymer blocks retaining their unsaturation on selective hydrogenation to enable the vulcanization of the block copolymer.

    摘要： 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.
