Abstract

The title compounds contain one or more fluorinated monomers and alkenyl isocyanurates and/or alkenyl cyanurates of the formulae ##STR1## wherein R.sup.1, R.sup.2, R.sup.4 and R.sup.5 independently of one another denote C.sub.3 -C.sub.6 -alkenyl having a terminal double bond and PA0 R.sup.3 and R.sup.6 independently of one another denote C.sub.3 -C.sub.6 -alkenyl having a terminal double bond or C.sub.1 -C.sub.5 -alkyl. The alkenyl (iso)cyanurates (I) and (II) are contained in the copolymers in an amount of 0.1-5 mol %. based on the number of moles of all the comonomers. The fluorinated monomers can also be partly replaced by comonomers which do not contain fluorine. The title compounds can be crosslinked after shaping and can then be used as elastic or dimensionally stable shaped articles.
