4-methylene-1,3-dioxolanes as cross-linking agents

   
   

The invention relates to: 4-methylene-1,3-dioxolanes of the general formula (I) ##STR1## wherein R1 denotes hydrogen, C.sub.5 -C.sub.6 -cycloalkyl or C.sub.1 -C.sub.4 -alkyl; m and n, which may be the same or different, denote 0 or 1, whereby m.ltoreq.n, o denotes 2, 3 or 4 depending on the valency of the group X; and X denotes a C--C single bond, straight-chain or branched C.sub.1 -C.sub.18 -alkylene, C.sub.5 -C.sub.6 -cycloalkylene, C.sub.8 -C.sub.18 -arylalkylene, --CH.sub.2 (OCH.sub.2 CH.sub.2).sub.p OCH.sub.2 --, --CH.sub.2 (OCH(CH.sub.3)CH.sub.2).sub.p OCH.sub.2 --, wherein p is an integer from 0 to 100; a process for their production; and intermediate products used. Moreover, compositions capable of emission-free, photocationic cross-linking, which comprise 4-methylene-1,3-dioxolanes of the general formula (I) and their use for the production of solvent-resistant and transparent films.
