Abstract
The present invention relates to a process for preparing a branched elastomeric polymer by polymerization of a conjugated diene in the presence of a specific branching agent and a specific stabilizing compound. The branched elastomeric polymer exhibits improved storage stability, as reflected by a constant, or less variable, polymer viscosity over time and with reduced temperature dependence.
