The silane-induced ring-opening polymerization of a cyclic siloxane, 1,1,3,3-tetramethyl-2-oxa-1,3-disilacyclopentane (2), is catalyzed by a ruthenium cluster, Mw/Mn = 1.5-3.0. The molecular weight of the polymer can be controlled by changing the concentration of the monomer solution. Addition of acetone results in formation of the polymer with Mn = 4400, spectroscopic analysis of which reveals existence of a siloxy and an isopropoxy moieties at the end group.
