Method of producing reactive silicon group-containing polyether oligomers

摘要

The invention provides a method of producing a reactive silicon group-containing polyether oligomer which comprises reacting (a) a polyether oligomer having main chain of a polyether and, in each molecule, at least one unsaturated group represented by the general formula (1): H2C=C(R<1>)-R<2>-O- (in the formula, R<1> is a hydrocarbon group containing not more than 10 carbon atoms and R<2> is a divalent organic group containing 1 to 20 carbon atoms and one or more species selected from the group consisting of hydrogen, oxygen and nitrogen atoms as a constituent atom) or the general formula (2): HC(R<1>) =CH-R<2>-O- on a side chain or at a terminus with (b) a reactive silicon group-containing compound in the presence of (c) a group VIII transition metal catalyst to introduce the reactive silicon group into said polyether oligomer (a), wherein the reaction is carried out in the presence of (d) a sulfur compound.
