Title:
ラジカル重合性含硫黄化合物およびラジカル重合性含硫黄ポリマー
Document Type and Number:
Japanese Patent JP4809020
Kind Code:
B2
Abstract:
To provide a radical-polymerizable sulfur-containing compound and a radical-polymerizable sulfur-containing polymer which give a useful cured product having a high refractive index as an optical material especially as lens.
The radical-polymerizable sulfur-containing compound comprises a group having a sulfur-containing heterocyclic 5-membered ring and at least one unsaturated group. The radical-polymerizable sulfur-containing polymer is obtained by performing cation ring-opening (co-)polymerization on the compound. Its manufacturing method, a composition containing the sulfur-containing compound and/or the sulfur-containing polymer, and cured products obtained from the composition are provided.
