Abstract
The present invention relates to curable solid particulate compositions that include: (a) a first reactant having at least two cyclic carbonate groups; and (b) a second reactant having at least two active hydrogen groups that are reactive with the cyclic carbonate groups of the first reactant. With some embodiments, the first reactant is a polyol residue having at least two cyclic carbonate groups, such as bisphenol A that has been reacted with epichlorohydrin, and in which the oxirane groups thereof have been converted to cyclic carbonate groups. The active hydrogen groups of the second reactant, with some embodiments, are each independently selected from hydroxyl groups, thiol groups, and amine groups. The curable solid particulate compositions, with some embodiments, are in the form of curable powder coating compositions.
