Polyoxyalkylene-modified diorganopolysiloxane compound, method for producing the same, and organopolysiloxane emulsion composition

摘要

Disclosed is a polyoxyalkylene-modified diorganopolysiloxane compound having a polyoxyalkylene-group-containing siloxane chain of formula (1) bonded to an end thereof, and including at least 40 structural units of formula (2) within the molecule thereof. (L is a double-chain polyoxyalkylene alkyl group represented by formula (3). (EO represents a polyoxyethylene group, AO represents a C3-10 polyoxyalkylene group, R2 represents a hydrogen atom, an alkyl group, a carboxy group, an acyl group, or a phenyl group, r = 0 to 10, s = 1 to 150, and t = 0 to 150.)] The present invention has excellent compatibility with high-polymerization-degree organopolysiloxanes. By using this polyoxyalkylene-modified diorganopolysiloxane compound as an emulsifier or an emulsification aid, a high-polymerization-degree organopolysiloxane can be emulsified easily.
