Mono- and di-cyclocarbonate telechelic polyolefins synthesized from ROMP using glycerol carbonate derivatives as chain-transfer agents

International audience; The ring-opening metathesis polymerization (ROMP) of cyclooctene (COE) has been achieved with Grubbs 2nd generation ruthenium catalyst in the presence of vinyl or acryloyl derivatives of glycerol carbonate. Such asymmetric chain-transfer agents enabled the synthesis in high yields of α-cyclocarbonate,ω-vinyl-poly(cyclooctene) (PCOE) and, more rewardingly, of the highly valuable α,ω-dicyclocarbonate telechelic PCOE.
