Title (EN) BATCH PROCESS FOR PREPARING MOLDED OPTICAL ARTICLES
(FR) PROCÉDÉ DISCONTINU DE PRÉPARATION D’ARTICLES OPTIQUES MOULÉS
Abstract:
(EN) A batch process for preparing a molded optical article includes introducing (i) a dithiol component or (ii) a polyisocyanate component into a reaction vessel; adding a first catalyst of organotin halide to form a first reaction mixture; heating the first reaction mixture; introducing a second catalyst of tertiary amine to the first reaction mixture; mixing a polyisocyanate (ii) into the reaction vessel containing the first reaction mixture if dithiol (i) was first added, or mixing a dithiol (i) into the first reaction mixture if the polyisocyanate (ii) was first added, to form a second reaction mixture; filling a mold with the second reaction mixture to provide a filled mold to form a molded optical article. The molar ratio of elemental tin present in the first catalyst to tertiary amine compound present in the second catalyst ranges from 0.04:1 to 0.29:1.
(FR) La présente invention concerne un procédé discontinu de préparation d’un article optique moulé comprenant l’introduction (i) d’un composant dithiol ou (ii) d’un composant polyisocyanate dans un récipient réactionnel ; l’addition d’un premier catalyseur d’halogénure d’organoétain pour former un premier mélange réactionnel ; le chauffage du premier mélange réactionnel ; l’introduction d’un second catalyseur d’amine tertiaire au premier mélange réactionnel ; le mélange d’un polyisocyanate (ii) dans le récipient réactionnel contenant le premier mélange réactionnel dans le cas d'ajout de dithiol en premier (i), ou le mélange d’un dithiol (i) dans le premier mélange réactionnel dans le cas d'ajout de polyisocyanate en premier (ii), pour former un second mélange réactionnel ; le remplissage d’un moule avec le second mélange réactionnel pour fournir un moule rempli afin de former un article optique moulé. Le rapport molaire de l’étain élémentaire présent dans le premier catalyseur au composé d’amine tertiaire présent dans le second catalyseur s’étend de 0,04:1 à 0,29:1.
