Docket No. A-8314 Paper No. 1 ACRYLATE-FUNCTIONAL ORGANOPOLYSILOXANES Abstract of the Disclosure Radiation polymerizable acrylate-functional organo- polysiloxanes having the formula Image where R is a radical selected from monovalent hydrocarbon radi- cals, 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 Image in which at least one R is a radical having the above formula, R1 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; R2 is hydrogen or a methyl radical; R3 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 R3 radical are selected from oxygen or nitrogen; R4 is a radical linked to the terminal oxygen or nitrogen atoms of R3 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 R3 is oxygen, then R4 may also be hydrogen. R5 is a monovalent hydrocarbon radical having from 1 to 20 carbon atoms or a radical of the formula -CH2-CH2-X wherein X represents -COOR6, -CONR6, -CN, -SO2R6, R6 is a mono- valent hydrocarbon radical having from 1 to 20 carbon atoms, a is a number having an average value of 0.7 to 2.6, b is a number of from 1 to 3, c is a number of from 0 to 4, d is a number of from 1 to 4, e is a number of from 0 to 4, x is a number of from 2 to 20,000 with the proviso that b + 1 = d + e. The acrylate-functional organopolysiloxanes are com- bined with a photosensitizer and/or peroxide and cured by radiation and/or heat. The compositions provided by the invention may be applied as coatings to substrates and polymerized by radiation and/or heat.
