Patent number: 7425599Abstract: Disclosed is a technology for the production of polyvinyl ethers having a reactive silicon-containing functional or atomic group at the terminal thereof. The polyvinyl ether as expressed by the formula (VII) is prepared by allowing, in the presence of a catalyst composed of a polynuclear ruthenium-carbonyl complex in which carbonyl groups coordinate with two to four ruthenium atoms, a vinylether compound expressed by the formula (III) to react with a silane compound expressed by the formula (IV). In the formulae, R1, R2 and R3 each represents a hydrogen atom or a hydrocarbon group having 1 to 8 carbon atoms, R4 represents an alkyl group, a cycloalkyl group, an aryl group, an aralkyl group, or a silyl group, and X1, X2 and X3 each represents a hydrogen atom, a halogen atom, an amino group, an alkyl group, an alkoxy group, a thioalkyl group, an alkylamino group, an aryl group, an arylamino group, an aralkyl group a vinyl group, or a heterocyclic group.Type: GrantFiled: June 10, 2003Date of Patent: September 16, 2008Assignee: Japan Science and Technology AgencyInventors: Hideo Nagashima, Kouki Matsubara
