Abstract

The polymerization of vinyl ethers (CH2=CHOR, R = nBu, iBu, tBu, iPr) is catalyzed by a ruthenium cluster, (μ323: η5-acenaphthylene)Ru3(CO)7 (1), using several hydrosilanes as the initiator to give polyvinyl ethers with M n = 2000-25 000 and Mw/Mn = 1.2-3.4. Spectroscopic analysis of the polymer reveals the existence of an organosilyl moiety at the end group, which is supported by UV and RI detection of GPC. The poly(tert-butyl vinyl ether) prepared by PhMe2SiD as the initiator contains a -CDHOtBu group at the other polymer end. These data suggest the polymer structure is R3Si-(CH2CHOR) n-H. Dominant heterotacticity was observed for the polymer structure, which was independent of organosilanes or solvents.
