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.dbd.CH.sub.2, --OCH.sub.2 CH.dbd.CH.sub.2, --SCH.sub.2 CH.dbd.CH.sub.2 or --NHCH.sub.2 CH.dbd.CH.sub.2 (n=1), --OH, --SH, --NH.sub.2, --COOH, --COCl or --OCO--C(R").dbd.CH.sub.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.
硫代二苯并酮羧酸酯、硫酯和具有式##STR1##中X、Y、Z、n和Q如专利要求中定义的具有反应性官能团的酰胺,其中Q是,例如,--OCH.dbd.CH.sub.2,--OCH.sub.2 CH.dbd.CH.sub.2,--SCH.sub.2 CH.dbd.CH.sub.2或--NHCH.sub.2 CH.dbd.CH.sub.2(n=1),--OH,--SH,--NH.sub.2,--COOH,--COCl或--OCO--C(R").dbd.CH.sub.2,其中R"是甲基或氢(n=2),适用于制备侧链中具有硫代二苯并酮基团的聚合物。可以将化合物(I)以及可以从中制备的聚合物用作光交联聚合物的感光剂或引发剂,如有需要,可以与胺混合物一起用于乙烯不饱和化合物的光聚合或聚烯烃的光化学交联。
