Abstract: The present invention relates primarily to polymers comprising at least one alkenyl aromatic monomer, at least one conjugated diene monomer, and at least one monomer containing silyl hydride moieties, characterized in that said polymers are hydrogenated and preferably functionalized by hydrosilylation reactions between the silyl hydride groups on the polymer chain and the multiple bonds of any alkene or alkyne compound. Besides the described products, this invention comprises their synthesis processes and their uses, especially as thermofusible adhesives, in plastics impact modification, and in chain-extension reactions to obtain new materials, among others.

Abstract: Homogeneous catalyst based on titanium compounds of the type (R1Cp)(R2Cp)Ti(PhOR3)2, where Cp is a cyclopentadienyl group, R1 and R2 are identical or different alkyl radicals (C3-C10), Ph is a phenyl group and OR3 is an alkoxyl group. Moreover, the invention relates to the use of said catalyst in a method for the hydrogenation of double bonds in unsaturated compounds, preferably polymers and/or copolymers of conjugated dienes, under mild reaction conditions.
