PURPOSE: An acrylic resin is provided to ensure excellent scratch property and good transparency as well as excellent fluidity. CONSTITUTION: An acrylic resin is prepared by polymerizing a monomer mixture consisting of 10-25 weight% of (meth)acrylic acid ester monomers, 50-80 weight% of vinyl aromatic compounds, and 10-25 weight% of vinyl cyanide compounds through a suspension polymerization method. The average molecular weight of the acrylic resin is 100,000-200,000. A melt index(MI) measured according to ASTM D1238 is 15-100. The scratch resistance measured according to JIS K5401 has the range of pensile hardness F or H. |
