Title
(EN) TRANSPARENT FILMS BASED ON RESIN COMPONENTS HAVING A HIGH GLASS TRANSITION TEMPERATURE
(FR) FILMS TRANSPARENTS À BASE DE COMPOSANTS DE RÉSINE À TEMPÉRATURE DE TRANSITION VITREUSE ÉLEVÉE
Abstract
(EN) Films having high light transmission values, low haze and high glass transition temperatures and useful, for example, as optical protection films and zero-zero optical retardation films, are prepared using one or more copolymers of methyl methacrylate having certain characteristics.
(FR) L'invention concerne des films présentant des valeurs de transmission de lumière élevée, un faible trouble et des températures de transition vitreuse élevées, et utiles, par exemple, en tant que films de protection optique et films de retardement optique zéro-zéro. Les films selon l'invention sont préparés au moyen d'au moins un copolymère de méthacrylate de méthyle doté de certaines caractéristiques.
