New organosilicon compounds are disclosed which contain (meth)acryloxy groups and consist of average units of the formula AaRbSiXcO4-(a+b+c) (I), ----------in which the radicals R are the same or different and represent monovalent, optionally halogenated hydrocarbon radicals having from 1 to 18 carbon atom(s) per radical, X is a radical which may be the same or different and represents a chlorine atom or a radical of the formula -OR1, where R1 represents an alkyl radical having from 1 to 8 carbon atom(s) per radical, which can be substituted by an ether oxygen atom, a is 0 or 1, with an average of from 0.01 to 1.0, b is 0, 1, 2 or 3, with an average of from 0.0 to 3.0, c is 0, 1, 2 or 3, with an average of from 0.0 to 3.0, the sum of a+b+c 4, and is an average of from 1.5 to 4.0, and A is a radical of the formula where x is 0 or 1 and y is 0 or 1, with the proviso that the sum of x+y is 1, z is 1, 2, 3 or 4, R2 represents a hydrogen atom or a methyl radical, R3 represents a radical of the formula -CH2CH2- or -C(CH3)HCH2- and R4 represents a linear or branched alkylene radical having from 1 to 6 carbon atom(s) per radical, with the proviso that the compounds contain at least one radical A per molecule. |
