Abstract
(EN)
Provided are a method for preparing a polyurethane optical resin and a use thereof. The preparation method comprises: subjecting a raw material composition containing isocyanate and a polymercaptan compound to a polymerization reaction so as to obtain a polyurethane optical resin, wherein the content of a dimer structure polymer of the isocyanate present in the isocyanate used in the raw material composition is controlled to be ≤ 4 wt%, preferably ≤ 3 wt%, further preferably ≤ 2.5wt%, and more preferably ≤ 1.6 wt%. The method for preparing a polyurethane optical resin provided in the present invention can successfully manufacture polyurethane optical resin, and can effectively reduce the rate at which optical deformation of an article occurs.

L'invention concerne un procédé pour la préparation d'une résine de polyuréthane optique et une utilisation de celle-ci. Le procédé de préparation comprend : l'opération consistant à soumettre une composition de matières premières contenant un isocyanate et un composé polymercaptan à une réaction de polymérisation de manière à obtenir une résine de polyuréthane optique, la teneur d'un polymère à structure dimère de l'isocyanate présent dans l'isocyanate utilisé dans la composition de matières premières étant réglée pour être ≤ 4 % en poids, de préférence ≤ 3 % en poids, de préférence encore ≤ 2,5 % en poids et plus préférablement ≤ 1,6 % en poids. Le procédé pour la préparation d'une résine de polyuréthane optique selon la présente invention permet de fabriquer avec succès de la résine de polyuréthane optique et permet de réduire efficacement la vitesse à laquelle se produit une déformation optique d'un article.
