Abstract
The present invention is a copolymer obtained by condensation, a condensation reaction of a leaving group and a nucleophilic group, of a mixture of the following (A) and (C) with a mixture of (B) and (D), or of a mixture of (A), (B), (C) and (D): (A) a monomer having two leaving groups and further at least one acid group in a molecule; (B) a monomer having two nucleophilic groups and further at least one acid group in a molecule; (C) a monomer having two leaving groups and substantially no acid group in a molecule; and (D) a monomer having two nucleophilic groups and substantially no acid group in a molecule.

A copolymer obtained by nucleophilic condensation of a mixture of the following (A) and (C) with a mixture of (B) and (D), or of a mixture of (A), (B), (C) and (D):
- (A) a monomer having two leaving groups and further at least one acid group in a molecule;
- (B) a monomer having two nucleophilic groups and further at least one acid group in a molecule;
- (C) a monomer having two leaving groups and substantially no acid group in a molecule;
- and
- (D) a monomer having two nucleophilic groups and substantially no acid group in a molecule.
A method of producing a copolymer, wherein a mixture of the following (A) and (C) with a mixture of (B) and (D) is condensed, or a mixture of (A), (B), (C) and (D) is condensed:
- (A) a monomer having two leaving groups and further at least one acid group in a molecule;
- (B) a monomer having two nucleophilic groups and further at least one acid group in a molecule;
- (C) a monomer having two leaving groups and substantially no acid group in a molecule:
- and
- (D) a monomer having two nucleophilic groups and substantially no acid group in a molecule.
