Abstract
PURPOSE: To obtain a water-dispersible resin having excellent pigment-miscibility, water resistance, corrosion resistance, drying characteristics, etc., by a method wherein a functional polymer is subjected to an esterification or an amidation reaction by using a tetrahydrophthalic anhydride compd, and the resulting modified polymer is neutralized with a basic substance.
CONSTITUTION: A radical-polymerizable monomer is polymerized in the presence of a basic polymer having at least one group selected from hydroxyl group, epoxy group and amino group in an org. solvent. The resulting functional polymer is subjected to an esterification reaction and/or an amidation reaction by using a tetrahydrophthalic anhydride compd. of the formula (wherein R is H, methyl). Then the resulting modified polymer is neutralized with a basic substance. As said basic polymer, a polymer contg. a hydroxyalkyl (meth)acrylate as a structural unit is preferred. As the modified polymer, a polymer having an acid value of 15W120 resulting from the esterification and/or amidation of 100pts.wt. functional polymer with 5W50pts.wt. tetrahydrophthalic anhydride compd. is preferred.
