Optionally liquid or solid paraffin or polyethylene wax is incorporated in an amount of 0.3 to 5% based on the total composition may be incorporated if a white article is desired.Molded articles prepared from these compositions, high in heat resistance and uniform appearance, even if the thickness of the molded article is small or uneven or the molding operation is carried out at a relatively low mold temperature, are also disclosed. Molding temperature dependence and thickness dependence on the heat distortion temperature of the molded article are remarkably improved as well.
