POLYMER, MOLDING MATERIAL AND RESIN MOLDED BODY

摘要

The present invention relates to: a polymer which is characterized by having a repeating unit represented by formula (1); a molding material which contains this polymer; and a resin molded body which is obtained by molding this molding material. In the formula, each of X1 and X2 independently represents an oxygen atom or a chemical single bond; each of r1-r3 independently represents a hydrogen atom or an alkyl group having 1-6 carbon atoms; Y represents a monovalent group having a specific composition; and each of n1 and n2 independently represents an integer of 1-4. The present invention provides: a novel polymer which is useful as a resin component for molded bodies for optical use; a molding material which contains this polymer; and a resin molded body which is obtained by molding this molding material.
