Biologically activated ion-exchange polymer salts are made by exchanging biologically active ionic agents onto ion-exchange polymers. The activated polymers are uniquely surface active and stable to thermal degradation and chemical and other forms of decomposition. The activated ion-exchange polymer salts may be processed and combined with polymer precursors using novel methods and materials to produce stable, biologically activated polymer composites, including antimicrobial and antifouling polymer composites.

The present invention addresses the problem of providing powder paint compositions and liquid paint compositions for baking, which have excellent corrosion resistance and workability as well as high durability and chemical resistance, and form a good lining film free from failures such as cracks; and a coating film and coated objects comprising such powder paint compositions or liquid paint compositions for baking. Powder paint compositions for baking comprise fluororesin where one or more types of porous coordination polymer (PCP)/metal-organic framework (MOF) formed by coordinate bonds between organic ligands and central metals disperse.

A superabsorbent polymer includes polymer particles, surface cross-linking agents and particles made of silicon-containing inorganic salt. The polymer particles have cross-linking inside the polymer particles. The surface cross-linking agents are covalently bound to the surface of the polymer particles so as to constitute a surface cross-linked region at the surface of each said resin particle, and the particles made of silicon-containing inorganic salt cover the surface of the polymer particles.
