ORGANOPOLYSILOXANE HAVING QUATERNARY AMMONIUM SALT-CONTAINING GROUP, METHOD FOR PRODUCING THE SAME, THICKENER, GELLING AGENT AND GEL-LIKE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a quaternary ammonium salt-containing group-containing organopolysiloxane without an amine odor, to provide a method for producing the organopolysiloxane and to provide a thickener, a gelling agent and a gel-like composition.;SOLUTION: The quaternary ammonium salt-containing group-containing organopolysiloxane is represented by an average unit formula: R¹_aR²_bSiO_(4-a-b)/2 (1) [wherein, R¹ is a monovalent hydrocarbon group or a monovalent substituted hydrocarbon group (except that corresponding to R²); R² is a quaternary ammonium salt-containing group-containing group represented by general formula: (R³)_c-O_dR⁴-(CH₂)₃N⁺(CH₃)₃X^- (2) (wherein, R³ is an alkylene group; R⁴ is a phenylene group which may be substituted with an alkyl group or an alkoxy group; c and d are each 0 or 1; and X is a halogen atom); and a and b are each 1≤a≤2.5; 0.0005≤b≤1.5]. The method for production comprises a reaction of a hydroxyphenyl group-containing organopolysiloxane with a glycidyltrimethylammonium salt. The thickener and gelling agent are composed of the organopolysiloxane. The gel-like composition is composed of a hydrophobic silicone oil and the organopolysiloxane.;COPYRIGHT: (C)2006,JPO&NCIPI
