Abstract
Abstract Thioxanthone carboxylic acid esters, thioesters and amides with reactive functional groups of the formula ##STR1## in which X, Y, Z, n and Q are as defined in the patent claim and Q is, for example, --OCH═CH 2 , --OCH 2 CH═CH 2 , --SCH 2 CH═CH 2 or --NHCH 2 CH═CH 2 (n=1), --OH, --SH, --NH 2 , --COOH, --COCl or --OCO--C(R")═CH 2 , 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 photocrosslinkable polymers or as initiators, if desired in a mixture with amines, for the photopolymerisation of ethylenically unsaturated compounds or for the photochemical crosslinking of polyolefines.
