<p>A process of preparing vesiculated polyester resin granules in which self-stabilising and selfvesiculating disperse particles of an unsaturated polyester resir., wherein the polyester contains 2-50% of poly(ethylene oxide) of average molecular weight 1.000 to 10,000 are polymerised in an aqueous medium to polymeric vesiculated granules. The aqueous slurry of granules may be dried to a soft powder. These granules are useful as a component in paint.</p> |
