A method for producing a branched conjugated diene polymer having an Mw / Mn of at least 1.1 by anionic polymerization, comprising the steps of: a) mixing a monomer mixture containing at least one conjugated diene and optionally at least one monoalkenyl arene compound with an anion initiator To form a living polymer; b) terminating the polymerization; And c) optionally functionalizing and / or hydrogenating the thus produced polymer, wherein the monomer mixture contains alpha, omega-bis (vinylphenyl) alkane as comonomer. The present invention also relates to the polymer thus obtained, the latex prepared therefrom, and the article made from the latex.
