摘要： Disclosed herein is an agent for absorbing and releasing water vapor, which comprises a homopolymer of at least one monomer selected from specific N-alkyl- or N-alkylene-substituted acrylamides and methacrylamides, a copolymer of two or more of the acrylamides and methacrylamides, a copolymer of said at least one monomer with one or more monomers other than the acrylamides and methacrylamides and copolymerizable therewith, or a water-insolubilized product of the homopolymer or either one of the copolymers. The above agent has broad utility for humidity contol of gases, humidity control in green houses and prevention of fogging on surfaces of transparent materials, as humidity sensors and dew sensors, etc.
