Abstract: A coating composition particularly suitable for coating poly(phenylene oxide) comprises aqueous medium-dispersed particles of: A) between about 30 and about 35 wt %, of a first styrene-acrylic polymer formed of monomers, between about 50 and about 80 mole % of which monomers are styrene or substituted styrene monomers, between about 2 and about 15 mole percent of which monomers are acrylonitrile, and between about 18 and about 48 mole percent of which are acrylic monomers, said first styrene-acrylic polymer having an acid number of about 15 or below; B) between about 30 and 35 wt %, of an acrylic second polymer formed of monomers, at least about 90 mole percent of which monomers are acrylate monomers, balance other &agr;, &bgr;-ethylenically unsaturated monomers, said acrylic second polymer having an acid number between 0 and about 25; and C) between about 30 and about 40 wt % of an acrylic-urethane hybrid polymer.

Abstract: Disclosed is a coating resin composition obtained by graft-polymerizing an unsaturated carboxylic acid to a chlorinated polyolefin in a solvent, esterifying all unsaturated carboxylic acid present in the reaction system, and mixing the obtained composition with a urethane prepolymer so that the weight ratio of the solids of the composition to the solids of the urethane prepolymer is in the range of from 90/10 to 10/90. This composition has a greatly improved gasoline resistance, smell generation is controlled and the storage stability at low temperature is high. The composition is effective as a general-purpose primer showing a high adhesion to inorganic materials, polar resins, non-polar resins, metals, and other materials.

Abstract: A process for extending the life of an antifouling paint film which comprises applying onto an antifouling paint film a coating of a water-permeable graft polymer prepared by polymerizing one or more vinyl monomers in the presence of a hydrophilic polymer. The coating of the water-permeable graft polymer has an excellent water-resistance and a proper water-permeability by which an antifouling agent contained in the antifouling paint film can be leached into sea water and moreover the leaching rate can be controlled. As a result, the antifouling property of the paint film is exhibited for a long period of time.
