Abstract
Disclosed are a process for producing a polymer composition having a high solubility in a solvent, and a polymer composition. The process for producing a polymer composition comprises polymerizing a radical polymerizable monomer in a solvent comprising a compound of formula (1) or (2) in the presence of a radical polymerization initiator:
