Sulfur-containing aromatic vinyl compound, crosslinked polymer articles and lens

摘要

A novel sulfur-containing aromatic vinyl compound represented by the following general formula (I) <IMAGE> [I] wherein R1 represents an alkylene group having 1 to 3 carbon atoms and R2 represents an alkylene group having 2 to 8 carbon atoms, and the two bonds in the benzene ring are meta or para to each other. A curable composition comprising at least one of the said vinyl compounds, an isocyanate compound and a radical polymerization initiator. On heating, the composition gives a crosslinked polymer article useful as lenses.
