Polyvinyl ethers having silicon-containing functional groups or atomic groups at the end and process for production thereof

摘要

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.
