Abstract:
1. A thermoplastic blow molding composition consisting of: a) 40 to 60 weight percent of a crystalline polyamide having a melting point of 200 to 320° C.; b) 60 to 40 weight percent of a polyetherimide having a glass transition temperature of 200 to 310° C. and a weight average molecular weight of 10,000 to 70,000 grams per mole as measured by gel permeation chromatography using a polystyrene standard; c) 0.2 to 1.0 weight percent of an organo phosphorus compound having only one phosphorus atom in its molecular structure, a molecular weight of greater than or equal to 500 grams per mole, and selected from the group consisting phosphonite, phosphite, phosphate and combinations of two or more of the foregoing organo phosphorus compounds; d) an additive comprising an alkali metal iodide, a copper salt, a hindered phenol compound, or a combination comprising two or more of the foregoing, and optionally e) an antioxidant, a stabilizer, a reinforcing filler, a colorant, a mold release agent, a lubricant, a smoke suppressor, an anti-drip agent, an ultra violet stabilizer, an electrically conductive filler or a combination comprising two or more of the foregoing, wherein the composition has a ratio of melt viscosity at a shear rate of 1 radian per second to a melt viscosity at 100 radians per second (rad/sec), of 4.0 to 12.0, at 330° C.; a reverse notched Izod impact strength of greater than or equal to 250 Joules per meter (J/m), and a heat distortion temperature, measured at 66 psi (0.45 MPa), of greater than or equal to 190° C.; and further wherein weight percent is based on the combined weight of polyimide and polyamide.
