The emulsion of copolymers of acrylates with epoxy group were preparedand characterized by means of swelling capacity. The self crosslinkingreaction of the copolymer was studied by FT-IR. It has been found that theswelling capacity of the crosslinked copolymer films decreased with increaseof the glycidyl methacrylate (GMA) content. The activation energy of thecrosslin-king reaction was obtained. A mechanism of the crosslinking reactionwas proposed.
