CA 1163271

Abstract Thioxanthone carboxylic acid esters, thioesters and amides with reactive functional groups of the formula Image (I) in which X, Y, Z, n and Q are as defined in the patent claim and O is, for example, -OCH=CH2, -OCH2CH=CH2, -SCH2CH=CH2 or -NHCH2CH=CH2 (n = 1), -OH, -SH, -NH2, -COOH, -COC1 or -OCO-C(R'')=CH2, in which R'' is methyl or hydrogen (n = 2), are suitable for the preparation of polymers with thioxanthone radicals in side chains. The compounds (I) and also the polymers which can be prepared therefrom can be employed as sensitisers for photocross- linkable polymers or as initiators, if desired in a mixture with amines, for the polymerization of ethylenically unsaturated compounds or for the photochemical cross- linking of polyolefines.
