Abstract
A shelf-stable polymer-producing coating powder composition is presented comprised of a cyclic nitrile compound and an organic compound containing at least two carboxyl or carboxylic acid anhydride groups or at least one carboxyl group and one carboxylic anhydride group, and a condensation-rearrangement catalyst. The preferred cyclic nitrile compounds are the cyclic nitrile carbonates, for example, adipodi(nitrile carbonate), and the preferred organic compounds are anhydride-containing polymers, for example, styrene-maleic anhydride copolymer. The coating powder composition preferably has a particle size of about 50 to 250 microns.
