ABSTRACT:
A nitrile resin composition having excellent transparency, antistatic properties and practical physical properties. The composition comprises (A) 80 to 97 wt. % of a nitrile resin which is obtained by graft copolymerization, in the presence of 3 to 30 parts by weight of a rubbery polymer containing at least 50 wt. % of a conjugated diene unit, of 100 parts by weight of a monomer mixture containing an unsaturated nitrile and an alkyl methacrylate, and has, as a matrix component, 65 to 80 wt. % of an unsaturated nitrile unit and 20 to 35 wt. % in total of an alkyl (meth)acrylate unit and a unit of a further monomer copolymerizable with the unsaturated nitrile and alkyl (meth)acrylate; and (B) 3 to 20 wt. % of a polyether ester amide, wherein the ratio of the melt viscosity of the component (A) to that of the component (B) at 210.degree. C. is 0.5 to 5 at a shear rate of 10.sup.2 sec.sup.-1 and 0.5 to 3 at a shear rate of 10.sup.3 sec.sup.-1 and the difference of the refractive index between the matrix component (A) to the component (B) is 0.2 or less.
