Abstract
The present invention relates to a polymer containing a structural unit based on a compound (A-a) represented by the following formula (1-a): (wherein R represents a hydrogen atom or CH3, X represents —CH2—, —O—, or —SO2—, l represents an integer of 1 or 2, and m1 and n1 each represents an integer of 0 or more, provided that the sum of m1 and n1 is 2), or formula (3): (wherein r represents 1 or 2, m2 represents an integer of 0 to 2, and n2 represents an integer of 1 to 3 provided that the sum of m2 and n2 is 2 or 3, a hydrogen atom in —CH2— being optionally substituted by another functional group). The polymer may contain a structural unit based on a vinyl monomer (B).
