摘要: A functionalized polyolefin and a tire tread composition comprising the functionalized polyolefin is described. The functionalized polyolefin comprises a vinyl/vinylidene-terminated polyolefin in which the vinyl/vinylidene terminus is functionalized with an alkoxysilane or an alkylsilane and optionally having ether, hydroxyl and/or amine functionality. The invention is also directed to the synthesis of vinyl/vinylidene-terminated polyolefins, functionalization at the vinyl/vinylidene terminus with an alkoxysilane or an alkylsilane and optionally having ether, hydroxyl and/or amine functionality.

摘要: A polymer obtained by a solution polymerization process comprising within a range from 0.5 to 20 wt % of cyclic olefin derived units, within a range from 0 wt % to 15 wt % C4 to C12 α-olefin derived units, the remainder being ethylene derived units; and having a Mw/Mn of less than 2.5; a weight average molecular weight (Mw) within a range from 80,000 to 300,000 g/mole; and a g′ value of greater than 0.95. The polymer may be formed in a solution polymerization process comprising combining in a solution cyclic olefins, ethylene, hydrogen and optionally C4 to C12 α-olefins with a single-site catalyst to form the polymer, wherein the single-site catalyst is most preferably selected from unsymmetrical Group 4 bis-bridged cyclopentadienyl metallocenes.

摘要: Rubber compounds may comprise: an epoxidized polypentenamer rubber (CPR) and/or a hydrolyzed epoxidized CPR; and a filler comprising silica particles. One nonlimiting example is rubber compound comprising: phr to 90 phr of a styrene-butadiene rubber (SBR), a natural rubber (NR), and/or a butadiene rubber (BR); 10 phr to 50 phr of a epoxidized CPR and/or a hydrolyzed epoxidized CPR; and 10 phr to 200 phr of a filler comprising silica particles, wherein the SBR, the NR, the BR, the epoxidized CPR, and the hydrolyzed epoxidized CPR combined equal 100 parts. Rubber compounds comprising epoxidized CPR and/or a hydrolyzed epoxidized CPR; and a filler comprising silica particles may be useful in tire compositions.
