<P>PROBLEM TO BE SOLVED: To provide an acrylic resin having high fluidity, processability, impact resistance, solvent resistance and heat resistance. <P>SOLUTION: An acrylic resin composition includes (A) an acrylic resin containing 80 to 99.5 mass% of a methacrylate ester monomer unit and 0.5 to 20 mass% of another vinyl monomer unit copolymerizable with at least one methacrylate ester, and satisfies the following conditions, and (B) a rubbery polymer. (I) The weight-average molecular weight measured by gel permeation chromatography (GPC) is 60,000 to 300,000. (II) Components having a molecular weight of ≤1/5 of a peak molecular weight (Mp) acquired by GPC elution curve account for 7 to 40% as an area ratio acquired by the GPC elution curve. <P>COPYRIGHT: (C)2012,JPO&INPIT |
