A polyester prepared by free radical polymerization of an unsaturated polyester prepolymer, wherein the polymerization occurs primarily by reaction of the unsaturation is disclosed. Coatings comprising the same are also disclosed, as are substrates coated at least in part with such coatings. La présente invention concerne un polyester préparé par polymérisation radicalaire d'un prépolymère de polyester insaturé, où la polymérisation se produit principalement par réaction de l'insaturation. La présente invention concerne en outre des revêtements comprenant celui-ci, ainsi que des substrats enduits au moins en partie avec de tels revêtements.
