Abstract
A polymer blend comprising: PA0 (A) an acrylic resin; PA0 (B) a block copolymer consisting essentially of a polymer block of a polymerized aromatic vinyl compound and/or a polymer block of a polymerized methacrylate monoester and a polyolefin polymer block; and PA0 (C) a polymer miscible with the acrylic resin (A) and immiscible with the block copolymer (B), wherein the absolute value (.vertline..eta..sub.AC -.eta..sub.B .vertline.) of the difference between the refractive index (.eta..sub.AC) of the blend of the acrylic resin (A) and the polymer (C) and the refractive index (.eta..sub.B) of the block copolymer (B) is 0.01 or less. This polymer block has excellent transparency, softness and other properties.
