A process for producing a polymer composition, comprising polymerizing a radical polymerizable monomer in a solvent containing a compound represented by formula (1) or (2) in the presence of a radical polymerization initiator:
- wherein R1 and R3 each independently represent hydrogen or a monovalent hydrocarbon group;
- R2 and R4 each independently represent a divalent hydrocarbon group, provided that R2 optionally represents nil;
- Y represents hydrogen, a monovalent hydrocarbon group or a hydroxyalkyl group;
- m is an integer of zero (0) or 1;
- n is an integer of 1 to 10;
- and X1 and X2 each independently represent any of the following divalent substituents:
- wherein R5 and R6 each independently represent hydrogen, a monovalent hydrocarbon group or a hydroxyalkyl group.
A polymer composition comprising polymer (A) represented by formula:
- wherein S represents a solvent-derived component;
- (M)p represents a polymer moiety comprising a radical polymerizable monomer unit M;
- and p is any integer.
A process for producing a polymer composition, comprising polymerizing a radical polymerizable monomer in a pigment dispersant or a pigment dispersant-containing solution in the presence of a radical polymerization initiator.
