Title (EN) N-HALOGENATED MALEIMIDE COPOLYMERS AND OPTICAL MATERIALS THEREOF
(FR) COPOLYMERES DE MALEIMIDES N-HALOGENES, ET MATIERES OPTIQUES AINSI OBTENUES
Abstract:
(EN) A copolymer containing N-halogenated phenyl maleimide units or N-halogenated phenyl bismaleimide units and one or more second units selected from halogenated acrylates, halogenated styrenes, halogenated vinyl ether, halogenated olefins, halogenated vinyl isocyanates, halogenated N-vinyl amides, halogenated allyls, halogenated propenyl ethers, halogenated methacrylates, halogenated maleates, halogenated itaconates, and halogenated crotonates, is useful to form optical devices.
(FR) La présente invention concerne une matière convenant particulièrement à la réalisation de dispositifs d'optique. Cette matière est essentiellement un copolymère contenant, d'une part des unités de phényl-maléimide N-halogénés ou des unités de phényl-bismaléimide N-halogénés, et d'autre part une ou plusieurs secondes unités. Ces secondes unités apaprtiennent au groupe des acrylates halogénés, styrènes halogénés, vinyl-éther halogénés, oléfines halogénées, isocyanates de vinyle halogénés, N-vinyl-amides halogénés, allyles halogénés, propényl-éthers halogénés, métacrylates halogénés, maléates halogénés, itaconates halogénés, et crotonates halogénés.
