摘要： 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.
摘要翻译：提供了制备光学膜用树脂组合物的方法。该方法包括通过使用连续本体聚合法使（甲基）丙烯酸烷基酯单体，含有苯环的丙烯酸酯类单体与（甲基）丙烯酸单体反应形成四组分共聚物; 以及通过在脱挥器中从反应产物中除去未反应的单体和溶剂，形成用于光学膜的树脂组合物。
