Patent

CA 2528763

A transparent shaped body is disclosed which is composed of a polythiourethane obtained by polymerizing monomer components containing the component (A) and component (B1) described below. Another transparent shaped body is also disclosed which is obtained by polymerizing monomer components containing the component (A), component (B1), component (B2) and component (C) described below. Component (A) is one or more polythiol compounds represented by the general formula (I): (I) (wherein m is 1, 2, 3, 4, 5 or 6). Component (B1) is one or more polyisocyanate compounds represented by the general formula (II): (II) (wherein n1, n2 and n3 are independently 3, 4, 5, 6, 7 or 8). Component (B2) is one or more aliphatic diisocyanate compounds having a ring structure in the molecule. Component (C) is an aliphatic diol compound.

L'invention a trait à un corps façonné transparent, qui est composé d'un polythio-uréthane obtenu par la polymérisation de composants monomères contenant le composant (A) et le composant (B1), décrits ci-après. L'invention concerne aussi un autre corps façonné transparent, qui est obtenu par la polymérisation de composants monomères contenant le composant (A), le composant (B1), le composant (B2) et le composant (C), décrits ci-après. Le composant (A) est un ou plusieurs composés polythiol représentés par la formule générale (I) (dans laquelle m est égal à 1, 2, 3, 4, 5 ou 6). Le composant (B1) est un ou plusieurs composés polyisocyanate représentés par la formule générale (II) (dans laquelle n¿1?, n¿2? et n¿3? sont égaux, indépendamment les uns des autres, à 3, 4, 5, 6, 7 ou 8). Le composant (B2) est un ou plusieurs composés diisocyanate aliphatiques possédant une structure cyclique dans la molécule. Le composant (C) est un composé diol aliphatique.
