applications for hydrogels, a better understanding of the relation between molecular structure and mechanical properties for well‐defined hydrogel is essential. A new library has been compiled of poly(ethyleneglycol) polymers (PEG) of different length end functionalized with diallyl, dithiol, and dimethacrylate, and crosslinked with complementary trifunctional crosslinkers. In this study, the hydrogels were initially

A paint composition being capable of forming a coating film which is remarkably excellent in stain-proofing property whereby neither stains in the air nor stains marked due to rain water adhere to or are deposited on the coating film surface and a stain-proofing agent for adding to the composition are provided. The paint composition comprises a stain-proofing agent comprising an organometallic compound represented by XbM(OR1)aR2c, its oligomer or cooligomer comprising two or more of the organometallic compounds; a resin for paints; and a curing agent and/or a curing catalyst, provided that a stain-proofing agent comprising a compound represented by the formula (2):
is excluded.
There is provided a fluorine-containing aqueous coating composition comprising (A) an aqueous emulsion of fluorine-containing resin having functional group which is obtained by dispersing, in water, a fluoroolefin copolymer having functional group prepared by solution polymerization method and (B) a water-dispersible unblocked isocyanate compound. The aqueous fluorine-containing resin coating composition is capable of curing at room temperature and can provide a coating film being excellent in chemical resistance, water resistance, solvent resistance, stain-proof property, hardness, weather resistance and durability.
