Abstract
A sulfur-containing aliphatic acrylic compound represented by the following general formula [I] ##STR1## wherein R.sup.1 represents a hydrogen atom or a methyl group, R.sup.2 represents an aliphatic hydrocarbon group having 1 to 8 carbon atoms, and R.sup.3 represents an aliphatic hydrocarbon group having 1 to 8 carbon atoms which may contain oxygen or sulfur in the main chain; a crosslinked polymer article obtained by polymerizing and curing a monomeric mixture composed of 100 to 60% by weight of at least one sulfur-containing aliphatic acrylic compound represented by the general formula [I] and 0 to 40% by weight of another copolymerizable monomer containing an ethylenic bond in a mold together with a radical initiator; a lens composed of the cross-linked polymer article thereof; and a process for producing a crosslinked polymer article thereof.
