    摘要: This provides an acrylic resin composition which has a high flowability and low melt viscosity and in which continuous fast molding can be carried out over a long period of time without staying in a molding machine, and by which a molded body having a suppressed whitening property without deterioration of the original properties such as appearance and mechanical strength can be obtained; and to provide a molded body thereof. The acrylic resin composition of the present invention is obtained by polymerizing a monomer, which comprises an alkyl methacrylate having an alkyl group with a carbon number of 1 to 4, in a presence of an elastomeric polymer obtained by polymerizing any one kind or two or more kinds selected from alkyl acrylates having an alkyl group with a carbon number of 1 to 8 and alkyl methacrylates having an alkyl group with a carbon number of 1 to 4 with a graft crossing agent; wherein the composition satisfies the predetermined flowability and light transmittance before and after tensile test.
