Branched Broad MWD Conjugated Diene Polymer

摘要

A process is provided for preparing a branched conjugated diene polymer with a molecular weight distribution Mw/Mn of at least 1.1, by anionic polymerization, comprising the following reaction steps: a) polymerizing a mixture of monomers comprising at least one conjugated diene and optionally one or more monoalkenyl arene compounds in the presence of an anionic initiator to form a living polymer; b) terminating the polymerization; and c) optionally functionalizing and/or hydrogenating the polymer so produced, wherein the mixture of monomers comprises an alpha,omega-bis(vinylphenyl)alkane as comonomer. The invention further relates to the polymer so obtained, a latex prepared therefrom, the latex, and articles made from the latex.
