<p>A cyclic sulfur compound having a structure represented by the following formula (3): (3) wherein R1 represents hydrogen, a reactive terminal group, or a linear, branched, or cyclic C1-10 (thia)alkyl, aryl, or aralkyl group having a reactive terminal group; R2 to R6 each independently represents hydrogen or an (un)substituted C1-10 monovalent hydrocarbon group; R represents an (un)substituted C1-10 divalent (thia)hydrocarbon group; n is an integer of 0 to 3; and Y represents any of oxygen, sulfur, selenium, and tellurium, provided that when Y is oxygen, then R1 is not a group having (meth)acryloyl. A polymerizable composition containing the compound gives a resin having a high refractive index, a high Abbe's number, and excellent impact resistance.</p> |
