Abstract
Provided is a copolymer rubber obtained by copolymerizing a butenedioic acid diester structure-containing monomer represented by General Formula (1) below and a radical polymerizable monomer: (in General Formula (1), R1 is a C1 to C4 alkyl group; R2 is a group represented by R7 or OR8; R7 is an optionally substituted C1 to C8 alkyl group; R3 is an optionally substituted C1 to C8 alkyl group or an optionally substituted polyalkylene glycol group; R3, R4, and R6 each independently represent a hydrogen atom or a C1 to C4 alkyl group; R5 is a hydrogen atom or a group represented by R3 or OR8; when R3 is a hydrogen atom, R2 is a group represented by OR3; R1 and R2 may be bonded to each other to form a ring; and R4 and R5 may be bonded to each other to form a ring).
