    Abstract: A method for manufacturing self-curing epoxy functionalized acrylic pressure-sensitive adhesives is provided to obtain epoxy functionalized acrylic pressure-sensitive adhesives with excellent adhesive strength through only heat treatment without using a crosslinking agent. A method for manufacturing self-curing epoxy functionalized acrylic pressure-sensitive adhesives comprises (a) a step for manufacturing a copolymer precursor by adding azobisbutyronitrile to the mixture containing 2-ethylhexylacrylate, butylacrylate, glycidyl methacrylate and acrylic acid; (b) a step for manufacturing a copolymer by reacting the copolymer precursor at 50~70 °C for 30 minutes to 2hours; and (c) a step for drying the copolymer and self-curing it at 70~170 °C for 20-40 minutes.
