摘要

An organo-Si cpd. (I) with (meth) acryloxy gps. contains units of formula AaRbSiXcO(4-(a+b+c))/2 (I'), where R = 1-18C (halogenated) monovalent hydrocarbon gp. or -R`-(OCH2CH2)o-(OCH(CH3)CH2)p-(O(CH2)4)q-OR"; R` = 1-8C alkylene; R" = H, 1-8C alkyl or -CO-R'''; R''' = 1-8C alkyl; o, p, q = 0-100; o+p+q = more than 0; X = Cl or -OR1; R1 = 1-8C alkyl, opt. substd. with an ether O atom; a = 0 or 1; b, c = 0-3; a+b+c = not above 4; A = a gp. of formula (II), pref. gp. of formula (III); z = 1-5; R2 = 1-8C alkylene, opt. contg. ether, amine, sulphide, ester, amide, urea and urethane gps.; R3 = H or Me; Y = H, 1-6C alkyl, -X, -CN, -NR42, -SR4, -O-CO-R4, -CO-OR4, -NR4-CO-R4, -CO-NR42 or NO2; and R4 is defined as R. The cpd. contains at least one (A) gp.
