ORGANOPOLYSILOXANE CONTAINING PLURAL KINDS OF ALKOXY GROUPS IN WHICH ORGANIC FUNCTIONAL GROUP AND NUMBER OF CARBON ATOMS DIFFER

摘要

PROBLEM TO BE SOLVED: To provide a new organopolysiloxane which can arbitrarily vary hydrolysis reactivity of alkoxysilyl groups in accordance with the intended use.;SOLUTION: This organopolysiloxane, containing plural kinds of alkoxy groups in which the organic functional group and the number of carbon atoms differ, is expressed by formula: Y_aR¹_bSi(OCH₃)_c(OC₂H₅)_d(OR²)_e(OH)_fO_{(4-a-b-c-d-e-f)/2}, wherein Y represents a mercapto group, epoxy group, (meth)acryloxy group, alkenyl group, haloalkyl group and/or amino group-containing organic group; R¹ represents an unsubstituted monovalent hydrocarbon group having no aliphatic unsaturated bond; R² represents an alkyl group having 3 and/or 4 carbon atoms; 0.01≤a≤1, 0≤b2, 0≤c≤2, 0≤d≤2, 0e≤2, 0≤f≤1, c+d≠0, 0.1≤c+d+e≤2.5, and 2≤a+b+c+d+e+f≤3.;COPYRIGHT: (C)2008,JPO&INPIT
