Abstract

The methacrylic resin of the present invention is prepared by using mercaptan and lactam as a coupling initiator, and is characterized by comprising an alkyl methacrylate unit and a methacrylamide unit, wherein the average molecular weight is in the range of about 50,000 to 500,000 g/mol and the glass transition temperature is in the range of about 125°C to 145°C.
