ABSTRACT:
A resin composition for optics is disclosed, which mainly comprises a graft copolymer comprising a styrene resin and an aromatic polycarbonate each having a specific molecular weight at a specific ratio of molecular weight and weight, said composition having a micro disperse phase of not more than 0.5 .mu.m. The resin composition has a reduced optical strain and an excellent micro disperse phase and is, therefore, suitable for use as optics.
