METHOD FOR PRODUCING BLOCK POLYMER, BLOCK POLYMERS, AND SURFACE TREATMENT AGENT

摘要

Disclosed is a method for producing block polymers which involves (i) a step for obtaining a polymer of first monomers by means of a first polymerization reaction to polymerize the first monomers in the presence of an alkoxyamine catalyst, and (ii) a step for obtaining a block polymer by means of a second polymerization reaction to polymerize second monomers in the presence of an alkoxyamine catalyst and the polymers of the first monomers, wherein at least one of the kinds of monomers is a fluorinated (meth)acrylate monomer. Obtained is a fluorinated polymer which is a block polymer having a glass transition temperature higher than conventionally possible. The fluorinated polymer can be used as an active ingredient of a surface treatment agent (for example, of a water and oil repellent, an antifouling agent, a mold release agent). The fluoropolymer has a high glass transition temperature, and has excellent water repellency, oil repellency, antifouling properties, and mold release properties.
