Elongated granules of reinforcing fibers extending generally parallel to each other longitudinally of the granule each of said fibers being substantially surrounded by a thermally stable, film forming thermoplastic adhesive comprising (a) a poly(C2-C6 alkyl oxazoline) in combination with (b) a poly (vinylpyrrolidone), provide complete dispersion of the fibers in thermoplastics during an injection molding cycle, conserving physical properties and providing significantly better EMI shielding than prior art extruder compounded resin/fiber blends.
