ELONGATED MOLDING GRANULES AND INJECTION-MOLDING PROCESS EMPLOYING THEM

摘要

ELONGATED MOLDING GRANULES AND INJECTION MOLDING PROCESS EMPLOYING THEM 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.
