Thermosetting compositions containing epoxy functional polymers prepared by atom transfer radical polymerization

摘要

A thermosetting composition comprising a co-reactable solid, particulate mixture of (a) epoxy functional polymer, and (b) co-reactant having functional groups reactive with the epoxy groups of (a), e.g., dodecanedioic acid, is described. The epoxy functional polymer is prepared by atom transfer radical polymerization and has 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.
