ABSTRACT:
It is an object of the present invention that a resin composition which has high chemical resistance while retaining high fluidity, is excellent in impact resistance, heat resistance, stiffness and heat stability and comprises an aromatic polycarbonate and polyethylene terephthalate, a molded product thereof and a process of manufacturing a car exterior material.This invention provides the resin composition which comprises 50 to 100 wt % of a resin component and 0 to 50 wt % of an inorganic filler (component D), whereinthe resin component is composed of (i) an aromatic polycarbonate (component A) having a specific viscosity average molecular weight and (ii) polyethylene terephthalate (component B) having a specific intrinsic viscosity (IV), a specific terminal carboxyl group content and a specific ratio (Mw/Mn) of weight average molecular weight (Mw) to number average molecular weight (Mn), and (iii) the weight ratio {(A+D)/B} of the total of the components A and D to the component B is 60/40 to 85/15, and a molded product thereof and a process of manufacturing a car exterior material.
