    摘要： 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 andR.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.

    摘要： An uncrosslinked copolymer of comonomers (a), (b) and (c) and containing reactive double bonds, the comonomers based on the total mols of (a), (b) and (c) comprising(a) 45 to 99.9 mol-% of at least one ethylene containing 1 to 4 fluorine atoms,(b) 0 to 54.9 mol-% of at least one comonomer selected from the group consisting of(b1) a linear or branched C.sub.3-8 alkene containing at least one fluorine atom,(b2) an alkyl vinyl ether containing at least one fluorine atom,(b3) an open-chain or cyclic C.sub.3-6 ketone containing fluorinated .alpha.,.alpha.'-positions and(b4) non-fluorinated C.sub.2-4 alkene, C.sub.3-6 alkyl vinyl ether or C.sub.4-6 vinyl ester, and(c) 0.1 to 5 mol-% of at least one unconjugated diene. They are produced by radical polymerization. Because of the absence of bromine and/or iodine, during subsequent peroxidic cross-linking no toxic alkyl bromide and/or iodide is released.
