Title Method of polymerizing a silalkylenesiloxane
Abstract Disclosed is a method for the preparation of a linear polysilalkylenesiloxane from four- to seven-membered cyclic silalkylenesiloxane by subjecting the cyclic silalkylenesiloxane to ring opening polymerization by using as a catalyst a polynuclear ruthenium-carbonyl complex in which carbonyl groups are coordinated with three or four ruthenium atoms, in the presence of a silane compound having at least one Si--H bond.
