Abstract:
Thermosetting composition comprises a compound having in the molecule two or more carboxyl groups blocked by a vinyl ether compound, a vinyl thioether compound or a hetero compound having a vinyl type double bond and oxygen or sulfur as the hetero atom, a compound having two or more reactive functional groups which can form a chemical bond with the blocked carboxyl compound by heating, a specific vinyl ether or vinyl thioether and a thermal latent acid catalyst. The blocked carboxyl group of the first compound and the reactive functional group of the second compound may be comprised in the same molecule. The thermosetting composition gives cured products having excellent chemical properties, physical properties, weathering resistance and storage stability and is advantageously utilized for coating compositions, ink, adhesive and molded plastics.

Abstract:
POLYMERS CONTAINING A NORBORNENYL GROUP ARE READILY CROSSLINKED BY IRADIATION TO PRODUCE INSOLUBLE PRODUCTS. THE CROSSLINKED PRODUCTS ARE USEFUL AS COATINGS ON WOOD, METAL, ETC., AS SELF-SUPPORTIN FILMS, WIRE INSULATION, FOR THE TREATMENT OF FBRICS TO RENDER THEM MORE DURABLE AND CREASE RESISTANT, AS WELL AS IN THE MANY KNOWN AREAS IN WHICH YNTHETIC POLYMERS ARE EMPLOYED SUCH AS THE PRODUCTION OF MOLDED AND EXTRUDED SHAPED ARTICLES.
Abstract:
An aqueous coating composition is provided that is preferably substantially free of styrene and structural units derived from styrene. The coating composition includes a resin system that preferably includes a water-dispersible polymer and an emulsion polymerized ethylenically unsaturated monomer component. The resin system is preferably formed using a process that includes emulsion polymerizing the ethylenically unsaturated monomer component in the presence of an aqueous dispersion including the water-dispersible polymer. In certain preferred embodiments, the water-dispersible polymer is a salt of an acid- or anhydride-functional aromatic polyether polymer.
