A Process for the preparation of polymer dispersions in hydroxylated polyesters.

摘要

A process based on a polymerization reaction of an ethylenically unsaturated monomeric compound in a hydroxylated polyester resulting from a polyesterification reaction of a polycarboxylic acid or a derivative thereof, with polyhydroxylated compounds containing from 0.001 to 0.5 mole % of an unsaturated monomer over the total of acid monomers comprising it; the amount of monomeric compounds ranges from 5% to 40% by weight of the reactants.
