ABSTRACT:
Thermoplastic molding compositions and articles comprise immiscible thermoplastic polymer components and reinforcing fibers. The immiscible thermoplastic polymer components and the fibers are blended together under high shear conditions The molding composition generally contains at least two phases and has an extremely smooth and fiber-free surface. Generally, other very good physical properties are obtained such as high heat distortion temperatures, high tensile modulus, high flex modulus, and the like are also very good. A desired blend of thermoplastic components is thermoplastic polyurethane and polyethylene terephthalate with glass fibers A polyethylene terephthalate copolyester blended with an immiscible thermoplastic polymer, preferably polyurethane, and glass fibers produces thermoplastic molding compositions and articles having surprisingly superior impact strength.
