Abstract

PURPOSE: To copolymerization of a monomer mixture containing a crosslinking functional group is conducted in the presence of a specific acrylic copolymer as a filler for the initial stage of the reaction to produce the titled resin of low molecular weight suitably used for high solid content paint in the form of high- concentration solution.
CONSTITUTION: When the copolymerization of a monomer mixture consisting of (A) 1W50wt% of a corsslinkable monomer such as β-hydroxyethyl acrylate and (B) 50W99wt% of an α,β-unsaturated monomer copolymerizable with component A such as methyl acrylate is carried out, (C) 5W30wt%, based on the above mixture, of an acrylic copolymer of 500W3,000 number-average molecular weight, preferably bearing the same functional group as that in component A, is added to the polymerization system and the copolymerization is effected at 140W200°C to produce the objective resin of more than 80% solid content and 500W5,000 number-average molecular weight.
