Title:
MANUFACTURE OF COPOLYMER AQUEOUS DISPERSION AND USE
Document Type and Number:
Japanese Patent JPS5819302
Kind Code:
A
Abstract:
An aqueous copolymer dispersion can be prepared, with a particular choice of the monomers and the ratios of their amounts, from styrene, esters of acrylic or methacrylic acid, vinyl esters, monomers containing hydroxyl groups, acrylic and/or methacrylic acid, acrylamide or methacrylamide and addition compounds of glycidyl esters of branched monocarboxylic acids with unsaturated carboxylic acids, by polymerization in the presence of an anionic emulsifier and a radical initiator and, if appropriate, a non-ionic emulsifier, which dispersion, in combination with an aminoplast resin, provides thermosetting coatings with excellent properties. These coatings provide highly elastic, weather-resistant, water-resistant surface coatings, which have high adhesion and are free of flaws, on metallic substrates.
