Patent ID: 7951887

Claim:
A process of producing a polymer, the process comprising: Step (1); preparing a polymer anion of an anionic polymerizable monomer from: an anionic polymerizable monomer; a compound represented by formula (1): (R1)nM (1) where: R1 represents a C1-C20 alkyl group or a C6-C20 aryl group, R1 may be the same or different when n is 2 or more, M represents an atom belonging to Group 2, 12, or 13 of the long form of the periodic table, and n represents the valency of M; and an anionic polymerization initiator; Step (2); preparing a polymer anion, in which the terminal is modified by a compound that forms a living carbanion capable of polymerizing an anionic polymerizable monomer by reacting with an anion, but which itself does not polymerize, by reacting the polymer anion prepared in Step (1) with a compound that forms a living carbanion capable of polymerizing an anionic polymerizable monomer by reacting with an anion, but which itself does not polymerize, wherein the compound that forms a living carbanion capable of polymerizing an anionic polymerizable monomer by reacting with an anion, but which itself does not polymerize, is a compound having a diphenyl ethylene backbone or stilbene backbone; and Step (3); reacting the polymer anion prepared in Step (2) with an acrylic monomer; wherein the acrylic monomer is at least one selected from the group consisting of methyl (meth)acrylate, ethyl (meth)acrylate, propyl (meth)acrylate, 2-hydroxyethyl (meth)acrylate, 2-hydroxy-3-phenoxyproyl (meth)acrylate, acrylonitrile, and methacrylonitrile.
