STUDY ON COPOLYMER EMULSION CONTAINING AN EPOXY GROUP

Methyl methacrylate, butyl acrylate, acrylic acid, and various amounts of glycidyl methacrylate (GMA) were copolymerized by a semicontinuous seeded emulsion copolymerization to be a four-component copolymer emu lsion; the copolymers were characterized using swelling capacity, tran smission electron microscopy (TEM), etc. The effect of glycidyl methac rylate and its content on the properties of emulsion and copolymer fil ms was studied. The self-crosslinking reaction of the copolymer was in vestigated by FTIR and DSC. It was found that the swelling capacity of the crosslinked copolymer films decreased with increase of the glycid yl methacrylate content, the morphology showed a core-shell structure, and the copolymer emulsion possessed a self-crosslinking property.
