Abstract
Radiation polymerizable acrylate- or methacrylate-functional organo-polysiloxanes having the structural formula ##STR1## wherein R is a radical selected from the group consisting of monovalent hydrocarbon radicals having from 1 to 20 carbon atoms, substituted monovalent hydrocarbon radicals having from 1 to 20 carbon atoms, monovalent hydrocarbonoxy radicals having from 1 to 20 carbon atoms and a radical of the formula: ##STR2## in which at least one R is a radical of formula (I), R.sup.1 is hydrogen or a methyl radical, R.sup.2 is selected from the group consisting of a multivalent hydrocarbonoxy radical and a multivalent hydrocarbonoxy radical containing non-terminal atoms selected from the group consisting of oxygen, sulphur and nitrogen atoms, R.sup.3 is a divalent hydrocarbon radical or a divalent hydrocarbonoxy radical, a is a number having an average value of from 0.7 to 2.6, b is a number of from 1 to 5, and x is a number from 2 to 1000. The acrylate- or methacrylate-functional organopolysiloxanes are combined with a photosensitizer and/or a peroxide and cured by radiation and/or heat. High energy electrons may be used in lieu of a photosensitizer or peroxide to cure these compositions.
