POLYMER HAVING SULFUR-CONTAINING CYCLIC STRUCTURE, RESIN COMPOSITION FOR OPTICAL MATERIAL AND MOLDED PRODUCT THEREOF, OPTICAL PARTS AND LENS

摘要

PROBLEM TO BE SOLVED: To provide a molded product which is high in both refraction and Abbe's number. Ž

SOLUTION: The polymer to use has a sulfur-containing cyclic structure having a repeating unit represented by formula (1) (wherein R1-R4are each hydrogen, an alkyl group, or a substituent group having oxygen or sulfur, and any one of R1-R4is a substituent group having a sulfur-containing cyclic structure which has sulfur as one of ring-composing atoms, or R1-R4bond to each others to form a sulfur-containing cyclic structure which has sulfur as one of ring-composing atoms; and m is 0 or 1).
