Abstract
A thermosetting epoxy resin was found to form polymer particles spontaneously in a stationary reaction system using polyethers as solvents. Poly(oxypropylene) and its copolymer with poly(oxyethylene) were effectively used as reaction media. The diameter of the resultant particles depended on the structure of the amines used as hardeners as well as on the molecular weight and composition of the polyether media. The glass-transition temperatures of the particles revealed that a small amount of polyether used as the medium was incorporated in the epoxy resin particles during the polymerization.
