Title (EN) OPTICAL PLASTICS AND METHODS FOR MAKING THE SAME
(FR) MATIERES PLASTIQUES OPTIQUES ET PROCEDES DE REPRODUCTION
Abstract:
(EN) Ophthalmic lens compositions comprising a cured polymer mixture of (A) an unsaturated polyester resin composition, (B) a monomer of formula (I); (C) an optional vinyl, acrylate monomer, or other monomer or mixtures thereof, and (D) a free radical generating catalyst system. Such a curable plastic material can form ophthalmic lenses of superior properties including high index of refraction which reduces the amount of material required for corrections.
(FR) Matières plastiques pour lentilles ophtalmiques comprenant un mélange polymère de (A) une résine polyester insaturée, (B) un monomère de formule (I), (C) éventuellement un vinyle, un monomère d'acrylate, ou un autre monomère ou leurs mélanges, et (D) un système catalyseur produisant des radicaux libres. Cette matière plastique polymérisable permet de produire des lentilles ophtalmiques présentant des propriétés supérieures, comprenant un indice de réfraction qui réduit la quantité de matière nécessaire pour les corrections.
