Abstract
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.
Claims21
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 and/or a polyfunctional chain transfer agent under ring opening metathesis polymerization conditions to form an unsaturated polyolefin reactive telechelic pre-polymer.
