Acrylic resin composition, and molded product and film made from same

A resin composition comprising:

• an acrylic resin;
• and
• a graft copolymer having a gel content of 65% to 84%,
• wherein the graft copolymer is a multistage-polymerized graft copolymer obtained by a multistage polymerization comprising the polymerization stages (I) to (III), the polymerization stages (I) to (III) being performed in an order such that the polymerization stage (I) is prior to the polymerization stage (II), and the polymerization stage (II) is prior to the polymerization stage (III),
• wherein, in the polymerization stage (I), 100 parts by weight of a first monomer mixture and 0.01 to 10 parts by weight of a polyfunctional monomer are polymerized in a presence of a primary alkyl mercaptan-based chain transfer agent and/or a secondary alkyl mercaptan-based chain transfer agent to obtain a first hard polymer, wherein the first monomer mixture comprises 40 to 100 wt % of a methacrylate ester and 60 to 0 wt % of a monomer having a double bond copolymerizable with the methacrylate ester,
• wherein, in the polymerization stage (II), 100 parts by weight of a second monomer mixture and 0.1 to 5 parts by weight of a polyfunctional monomer are poloymerized to obtain a soft polymer, wherein the second monomer mixture comprises 60 to 100 wt % of an acrylate ester and 40 to 0 wt % of a monomer having a double bond copolymerizable with the acrylate ester, and
• wherein, in the polymerization stage (III), 100 parts by weight of a third monomer mixture and 0 to 10 parts by weight of a polyfunctional monomer are polymerized to obtain a second hard polymer, wherein the third monomer mixture comprises 60 to 100 wt % of a methacrylate ester and 40 to 0 wt % of a monomer having a double bond copolymerizable with the methacrylate ester.
