Document Type and Number:
Japanese Patent JP6674536
Kind Code:
B2
Abstract:
An exemplary polymerizable thermosetting composition includes the reaction product of (a) allyl alcohol; (b) a cyclic polyol selected from the group consisting of a cycloaliphatic polyol having at least one secondary hydroxyl group, a heterocyclic polyol having primary and/or secondary hydroxyl groups, and mixtures thereof; (c) ethyleneglycol bischloroformate; and (d) optionally, at least one linear or branched aliphatic polyol having two to six hydroxyl groups. The allyl alcohol (a) is present in an amount of 0.4 to 1.99 equivalents of OH to 1 equivalent chloroformate, and the cyclic polyol (b) is present in an amount of 0.01 to 0.6 equivalents of OH to 1 equivalent of chloroformate. A reaction product, a polymerizate including the polymerizable thermosetting composition, and an optical article including the polymerizable thermosetting composition are also provided.
