Abstract

La présente invention concerne des compositions contenant un métal ayant des indices de réfraction d'au moins 1,5 comprenant une unité précurseur contenant un métal (UM), une unité prépolymère (UP) et un catalyseur ou initiateur capable d'induire une réaction de combinaison des groupes fonctionnels à insaturation éthylénique de l'unité précurseur contenant un métal et des groupes fonctionnels réactifs de l'unité prépolymère. Dans un autre mode de réalisation, la composition comprend des UM et un catalyseur ou initiateur capable d'induire une réaction de combinaison des unités précurseurs contenant un métal. L'UM et l'UP contiennent toutes deux des groupes fonctionnels supplémentaires, lesquels peuvent être sélectionnés pour obtenir une compatibilité de l'une avec l'autre et pour produire des films optiquement transparents. Les compositions contenant un métal peuvent être utilisées pour produire des films ou articles ayant un facteur de transmission d'au moins 90 % et un indice de réfraction compris dans l'intervalle de 1,5 à 1,8 pour la lumière dans la plage 400-700 nm et de 1,5 à 2,4 pour la lumière dans la plage 150-400 nm.
