A process for the production of a vinyl polymer containing a tertiary amino group, which comprises subjecting (a-1) a vinyl polymer containing a carboxylic anhydride group obtained by copolymerizing maleic anhydride, itaconic anhydride or mixtures thereof with at least one copolymerizable monomer and (a-2) a compound containing both one primary amino group and one tertiary amino group for each molecule to a ring-opening reaction, and dehydrocyclizing the adduct to form an imide ring containing polymer. A curable resin composition comprising the resulting polymer and a polyepoxy compound as essential ingredients.
摘要:
A room temperature-curable resin composition consisting essentially of (A) a vinyl polymer containing a basic nitrogen atom and (B) a compound containing both an epoxy group and a hydrolyzable silyl group in each molecule. The composition is especially useful as a paint, an adhesive, or a sealing agent.
摘要:
A water-dispersible polyisocyanate composition comprises a hydrophobic polyisocyanate (A) and a vinyl polymer (B) having a nonionic group and an isocyanate group, in which the hydrophobic polyisocyanate (A) can be dispersed in a water-based medium by the vinyl polymer (B) having a nonionic group and an isocyanate group. The water-dispersible polyisocyanate composition is produced by reacting a hydrophobic polyisocyanate with a vinyl polymer (b) having a nonionic group and an active hydrogen group-containing group capable of reacting with an isocyanate group at a molar ratio of the isocyanate group to the active hydrogen group-containing group of 3 to 350.

摘要:
The present invention proposes highly practical curable resin compositions for use in water based paints, which contain no, or much less organic solvent when compared with current organic solvent based paints, and which produce painted surfaces which have excellent curability and weather resistant properties, as well as excellent resistance to solvents, chemicals and water. These curable resin compositions include a compound combining both epoxy and hydrolyzable silyl groups, and a water based product obtained by dispersing or dissolving in water, a tertiary amino vinyl polymer, a vinyl polymer containing both tertiary amino and acidic groups, or an acidic vinyl polymer, which has been either partially or completely neutralized by an acidic or basic compound.
