Abstract: A composition that contains from 30 to 95 wt. %, based on the total weight of the composition, of a thermoplastic component and an effective amount of a flow-enhancing component. The effective amount of the flow-enhancing component reduces the viscosity of the composition by at least 10% compared to the viscosity of a composition comprising the thermoplastic component, but not an effective amount of the flow-enhancing component. The thermoplastic component is selected from the group consisting of polycarbonates, polyesters, and combinations thereof. The flow-enhancing component comprises b1) a component selected from the group consisting of metal oxides, metalloid oxides, metal alkoxides, metalloid alkoxides, and combinations thereof and b2) a mineral filler component. The weight ratio of component b1) to component b2) ranges from 1:25 to 25:1. A method for enhancing the flow of compositions comprising thermoplastic components is also disclosed.

Abstract: A thermoplastic composition comprises, based on the total weight of the composition: 51-90 wt % polyester, 10-49 wt % ABS impact modifier; 0-20 wt % omultifunctional epoxy compound; 0-40 wt % filler; 0-2 wt % fibrillated fluoropolymer; and more than 0 to 5 wt % of a stabilizer composition. An article blow molded or injection molded from the composition has a multi-axial impact total energy from 30-100 Joules at ?30° C. and a ductility of more than 90%; a permeability of more than 0 and less than or equal to 1.5g/m2-day to ASTM D 471-98 Fuel C, measured after exposure to ASTM D 471-98 Fuel C vapor for 20 weeks at 40° C.; an MVR of 1-20 cc/10 min., measured at 265° C.; a flexural modulus of greater than 1300 MPa; and retains at least 75% of its initial tensile elongation at break, after exposure to Fuel E85 for 28 days at 70° C.
