POLYMER, METHOD FOR PRODUCING POLYMER, RESIN COMPOSITION FOR OPTICAL MATERIAL, MOLDED BODY, OPTICAL MATERIAL AND LENS

摘要

PROBLEM TO BE SOLVED: To provide a resin material which has a high refractive index, low dispersibility (high Abbe's number), high heat resistance, high light transmittance and low water absorptivity.

SOLUTION: The polymer includes a repeating unit having aliphatic polycyclic structures. The aliphatic polycyclic structures bond with atoms composing the main chain in the repeating unit via one atom of oxygen or one atom of sulfur, and also, the repeating unit has an aliphatic ring including a sulfonyl group as the constitutional group of a ring skeleton.
