A PROCESS TO PRODUCE A POLYOLEFIN REACTIVE TELECHELIC PRE-POLYMER, POLYOLEFIN REACTIVE TELECHELIC PRE-POLYMERS AND CROSSLINKED ELASTOMERS AND HIGH MOLECULAR WEIGHT ELASTOMERS

摘要

Preparation of a polyolefin-reactive telechelic prepolymer comprising reacting an alkyl-cis-cyclooctene and optionally cis-cyclooctene under ring-opening metathesis polymerization conditions in the presence of a bifunctional chain transfer agent to form an unsaturated polyolefin-reactive telechelic prepolymer. How to do it is provided. Further provided are unsaturated and hydrogenated reactive prepolymers, crosslinked elastomers and high molecular weight elastomers.
