<p>This invention provides a polymer comprising constitutional units based on a compound (A-a) represented by formula (1-a) or formula (3): [Chemical formula 1] (1-a) wherein R represents a hydrogen atom or CH<SUB>3</SUB>; X represents -CH<SUB>2</SUB>-, -O- or -SO<SUB>2</SUB>-, l is an integer of 1 or 2, and m1 and n1 are an integer of 0 or more, provided that m1 + n1 = 2; and [chemical formula 2] (3) wherein r is 1 or 2, m2 is an integer of 0 to 2, n2 is an integer of 1 to 3, m2 + n2 is 2 or 3, and hydrogen atoms in -CH<SUB>2</SUB>- are optionally substituted by other functional group. The polymer may contain constitutional units based on vinyl monomer (B).</p> |
