Abstract:
Provided is a method of preparing a resin composition for an optical film. The method includes forming a four-component copolymer by reacting an alkyl(meth)acrylate-based monomer, an acrylate-based monomer containing a benzene ring, and a (meth)acrylic acid monomer by using a continuous bulk polymerization method; and forming a resin composition for an optical film by removing unreacted monomer and solvent from a reaction product in a devolatilizer.
