Development of catalyst systems for synthesizing diene rubbers with vinyl structure

摘要

Synthesis of rubber materials with new structure has always been a challenge from the tire industry, where the performance of rubber has been asked to be higher and higher. The presentation includes a brief review on catalyst systems, polymerization behaviors and properties of diene rubbers having pendent double bonds in chain structure, and our recent results on synthesizing vinyl polybutadiene and 3,4-polyisoprene rubbers with a novel iron-based catalyst system as well.
