Various embodiments of the present invention are directed to switchable carboxybetaine-based polymers, hydrogels, and/or elastomers, along with novel related monomers, crosslinkers, and methods. Under acidic conditions, the materials undergo self-cyclization and can catch and kill bacteria. Under neutral/basic conditions, these materials undergo ring-opening and can release killed bacterial cells and resist protein adsorption and bacterial attachment. These smart polymers, hydrogels and elastomers also show excellent mechanical properties making them highly desirable for many biomedical applications.

Polymers including multi-stage polymers that combine the structural integrity of a polymer with a high glass transition temperature (Tg) with a softer, lower molecular weight polymer that coalesces quickly and is flexible to maintain scrubbability are disclosed. Architectural compositions containing these film-forming polymers exhibit anti-blocking properties within one hour from being applied to a substrate.

The polymer material of the invention is an amine-containing polymer that contains a polymer of a monomer mixture consisting of a monofunctional monomer and more than 10 mol% and 30 mol% or less of a polyfunctional monomer, and exhibits a large reversible gas absorption amount though having a low water content. An efficient production method for the polymer material of the invention includes a polymer synthesis step of synthesizing a polymer by polymerizing monomers in a reaction mixture containing a monofunctional monomer, a polyfunctional monomer, a solvent and an initiator, and an amine infiltration step of infiltrating an amine-containing processing liquid into the polymer, wherein the total monomer concentration in the reaction mixture is 0.7 mol/L. or more, the proportion of the polyfunctional monomer among the monomers contained in the reaction mixture is 10 to 30 mol%. When the monofunctional monomer has an amino group, the amine infiltration step can be omitted.
