Facile, efficient functionalization of polyolefins via controlled incorporation of terminal olefins by repeated 1,7-octadiene insertion
Exclusive repeated insertion of 1,7-octadiene (OD) has been achieved in OD polymerization using (C5Me5)TiCl2(0-2,6-(i) Pr2C6H3)-MAO catalyst to afford polymers containing terminal olefinic double bonds in the side chain. Copolymerization of OD with 1-octene using the same catalyst afforded high molecular weight copolymers containing terminal olefins, and quantitative introduction of hydroxyl group could be achieved upon treatment of the copolymer with 9-BBN/NaOH-H2O2 (aq); ring-opening polymerization of epsilon-caprolactone could be initiated in a controlled manner from the hydroxyl group after treatment with AlEt3.
