PROCESS FOR PRODUCTION OF POLYMER EMULSIONS Abstract of the Disclosure A process is disclosed in the specification for the production of a polymer emulsion comprising polymerizing at least one partially esterified, imidated or amidated product of an adduct with a compound having an polymerizable unsaturated group and a hydroxy group, epoxy group or amino group, in an aqueous system in the presence or absence of a vinyl monomer, the adduct being produced by adding an .alpha.,.beta.-unsaturated dicarboxylic acid, or an anhydride thereof, to at least one compound selected from the following group: a synthetic unsaturated polymer having a number average molecular weight of 150 to 30,000 and an iodine value of 50 to 500, a natural drying oil, a natural semidrying oil and an unsaturated fatty acid which composes the natural drying or semidrying oils. The polymer emulsion thus obtained shows excellent coating film properties when used for paints. |
