Abstract

The polymerization of vinyl ethers (CH₂=CHOR, R = ⁿBu, ⁱBu, ^tBu, ⁱPr) is catalyzed by a ruthenium cluster, (μ₃,η²:η³: η⁵-acenaphthylene)Ru₃(CO)₇ (1), using several hydrosilanes as the initiator to give polyvinyl ethers with M _n = 2000-25 000 and M_w/M_n = 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 -CDHO^tBu 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.
