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.
本发明涉及一种在特定支化剂和特定稳定化合物存在下通过共轭二烯聚合制备支化 弹性聚合物的工艺。支化弹性聚合物具有更好的贮存稳定性,具体表现为聚合物粘度随时间的变化恒定或变化较小,温度依赖性降低。
