摘要：
A thermosetting composition comprising a co-reactable solid, particulate mixture of (a) polycarboxylic acid functional polymer, and (b) epoxy functional polymer, is described. The polycarboxylic acid functional polymer and epoxy functional polymer are each prepared by atom transfer radical polymerization and have well defined polymer chain architecture and polydispersity index of less than 2.5. The thermosetting compositions of the present invention have utility as powder coatings compositions.
