Abstract:
A polymer blend with good softness comprising:(A) an acrylic resin having a methyl methacrylate unit content ranging from 80 to 100% by weight;(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(C) at least one polymer selected from the group consisting of styrene/acrylonitrile copolymer, a phenoxy resin and a styrene/maleic anhydride copolymer miscible with acrylic resin (A) and immiscible with 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 (ROB) of the block copolymer (B) is 0.01 or less; andwherein said blend is obtained by melt mixing of components (A), (B) and (C).
