ABSTRACT:
Radiation polymerizable acrylate-functional organopolysiloxanes having the formula ##STR1## where R is a radical selected from monovalent hydrocarbon radicals, substituted monovalent hydrocarbon radicals having from 1 to 20 carbon atoms or monovalent hydrocarbonoxy radicals having from 1 to 20 carbon atoms, or a radical of the formula ##STR2## in which at least one R is a radical having the above formula, R.sup.1 is a divalent radical selected from a saturated divalent hydrocarbon radical having up to 20 carbon atoms, a divalent hydrocarbonoxy radical in which the oxygen is in the form of an ether linkage and an unsaturated divalent hydrocarbon radical having from 3 to 10 carbon atoms; R.sup.2 is hydrogen or a methyl radical; R.sup.3 is a linear or branched radical having 2, 3, 4, 5 or 6 valences in which the radical is selected from a substituted hydrocarbon radical, or a hydrocarbon ether or thioether radical having one or more repeating units and the terminal atoms of the R.sup.3 radical are selected from oxygen or nitrogen; R.sup.4 is a radical linked to the terminal oxygen or nitrogen atoms of R.sup.3 and is selected from the group consisting of a monovalent hydrocarbon radical having from 1 to 20 carbon atoms, an acryloyl radical, and a substituted acryloyl radical and when the terminal atom of R.sup.3 is oxygen, then R.sup.4 may also be hydrogen. R.sup.5 is a monovalent hydrocarbon radical having from 1 to 20 carbon atoms or a radical of the formula
