METHOD FOR PRODUCING REACTIVE SILICON GROUP-CONTAINING POLYETHER OLIGOMER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a reactive silicon group-containing polyether oligomer in a short time by which mixing performances required for dispersion of a catalyst and a reactive silicon group-containing compound are satisfied. SOLUTION: This method for producing the reactive silicon group-containing polyether oligomer is characterized by using a stirred tank equipped with a rotation stirring shaft having a flat plate blade in the stirred tank and installed so as to be drivable from the outside of the vessel in reacting a polyether oligomer having unsaturated groups with the reactive silicon group-containing compound in the presence of a group VIII transition metal catalyst in the stirred vessel and producing the reactive silicon group-containing polyether oligomer.
