Abstract

Procedure for raising the molecular weight of a polymer of a conjugated diene and/or a vinylaromatic hydrocarbon by reacting under coupling conditions such a polymer, which contains one or more alkali metal atoms terminally linked to a coupling reagent that reacts with the atoms of alkali metal coupling two or more molecules of such polymer, characterized in that the coupling reagent is an ester of an unsaturated acid and has the formula: **(See formula)** where R is hydrogen or alkyl, cycloalkyl or aralkyl containing from 1 to 12 carbon atoms and R'is alkyl, cycloalkyl or aralkyl containing up to 12 carbon atoms.
