摘要： Compositions of coreactant resins and polyanhydrides that contain a central moiety and more than one non-cyclic anhydride moiety are cured to provide coatings that have good exterior durability. Preferred high molecular weight polyanhydrides contain a central polymer moiety that has no more than 25 weight percent repeating units derived from unsaturated aliphatic hydrocarbon monomers. In other preferred polyanhydrides, the anhydride moieties are linked to a central moiety by an ester moiety.
