Stimuti-responsive polymer utilizing keto-enol tautomerization and stimuli-responsive separating material and chemical-releasing capsule comprising the same

摘要

A stimuli-responsive polymer derivative utilizing keto-enol tautomerization. Also disclosed are a simple process for producing an N-acyl(meth)acrylamide derivative which can be used as a monomer for the stimuli-responsive polymer, a process for the production of an intermediate thereof, and an intermediate thus produced.
