Preparation of Epoxy Acrylate Emulsion Using Mixed Surfactants and Its Polymerization
A:series of epoxy acrylate emulsions were prepared with several surfactants ranging from HLB 12 to 14 at 40 degrees C. For epoxy acrylate emulsion, additives and conditions were established among factors : HLB value of emulsion, agitation speed, water dropping speed, and dropping amount of the deionized water. For emulsion polymereization with water soluble initiator KPS, emulsion was broken during polymerization, because interfacial complex formed by association of surfactant with co-surfactants stabilizing emulsion was weakened by interpenetration of radicals formed at aqueous. Accordingly, the polymerization of epoxy acrylate emulsion was carried out by using oil soluble initiator, AIBN, and the conversion changes with. initiator concentration and HLB values were investigated.
