PROBLEM TO BE SOLVED: To provide a polymer composition that contains an acrylic resin and a block copolymer comprising a vinyl aromatic compound polymer block and an olefin polymer block, shows excellent processability, resistance to weather, color development, colorability and flexibility with much increased transparency. SOLUTION: This polymer composition (i) comprises (A) an acrylic resin, (B) a block copolymer having at least one selected from a vinyl aromatic compound polymer block and a methacrylate monoester polymer block and a polyolefin polymer block and (C) a polymer that is compatible to (A) the acrylic resin but incompatible to (B) the block copolymer and (ii) the absolute difference (|nAC-nB|) in the refractive index between the blend polymer of the acrylic resin (A) and the polymer (C) (nAC) and the block copolymer (B) (nB) is <=0.01.
