Abstract
Photosensitized silicones having the formula MD,D,D*,M are provided, wherein M is selected from the group consisting of R,SiO,and R,ESiO,; wherein each R is independently selected from the group consisting of monovalent hydrocarbon radicals having from 1 to 30 carbons, and E is an epoxide functionalized substituent selected from the group of epoxy either substitutents having the formula C,H,O,or the group of alkyl cyclohexeneoxide substituents having the formula C,H,O; D has the formula R,SiO,, wherein each R is independently selected from the group consisting of monovalent hydrocarbon radicals having from 1 to 30 carbons; D,has the formula RESiO,wherein R is selected from the group consisting of monovalent hydrocarbon radicals having from 1 to 30 carbon atoms, and wherein E is an epoxide functionalized substituent selected from the group of epoxy ether substituents having the formula C,H,O,or the group of alkyl cyclohexeneoxide substituents having the formula C,H,O; D* is defined as the reaction product of D,with a compound selected from the group consisting of R′COOH, (R′CO),O, R′COX, R′SO,H, and R′SO,X wherein R′ is a photosensitizing naphthalene substituent and X is a halogen; and wherein the subscripts n, m, and p are integers where the sum of n+m+p ranges from about 10 to about 2,000. A method for preparing the photosensitized silicones is also provided.
