A resin composition is disclosed which comprises: (a) from 1 to 99% by weight of a maleimide-olefin copolymer comprising from 40 to 60 mol % of structural unit (I) shown below and from 60 to 40 mol % of structural unit (II) shown below and having a number-average molecular weight of from 1x103 to 5x106: <IMAGE> (I) wherein R1 is hydrogen or an alkyl having 1 to 6 carbon atoms, <IMAGE> (II) wherein R2 and R3 each is hydrogen or an alkyl having 1 to 6 carbon atoms; and (b) from 99 to 1% by weight of an acrylonitrile-styrene copolymer containing from 21 to 45% by weight of an acrylonitrile units. The composition is excellent in optical properties including transparency and low birefringence and in heat resistance and mechanical properties. |
