摘要 |
<p>The invention relates to 4-methylene-1,3-dioxolanes of the general formula (I) <CHEM> wherein R1 denotes hydrogen, C5-C6-cycloalkyl or C1-C4-alkyl; m and n, which may be the same or different, denote 0 or 1, whereby m≤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 C1-C18-alkylene, C5-C6-cycloalkylene, C8-C18-arylalkylene, -CH2(OCH2CH2)pOCH2-, -CH2(OCH(CH3)CH2)pOCH2-, 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.</p> |
