Process for producing reactive telechelic prepolymer of polyolefin, reactive telechelic prepolymer of polyolefin, crosslinked elastomer and high molecular weight elastomer

摘要

A process to produce a polyolefin reactive telechelic pre-polymer comprising reacting alkyl-cis-cyclooctene and optionally cis-cyclooctene, in the presence of a difunctional chain transfer agent under ring opening metathesis polymerization conditions to form an unsaturated polyolefin reactive telechelic pre-polymer is provided. Further provided are unsaturated and hydrogenated reactive pre-polymers, crosslinked elastomers and high molecular weight elastomers.
