PROCESS FOR PRODUCING PELLETS OF GLASS-FIBER-REINFORCED THERMOPLASTIC RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a process for producing pellets of a glass-fiber-reinforced thermoplastic resin composition with which the productivity of pellets of a glass-fiber-reinforced thermoplastic resin composition can be rendered higher than in conventional processes and the probability that monofilament masses (unfibrillated glass-fiber bundles) remain in the produced pellets can be minimized.

SOLUTION: A screw for kneading thermoplastic resin and glass fibers includes a screw element having a specific shape. The specific screw element is a single-thread progressive screw element which has a flight part having circular-arc-shaped notches that satisfy specific requirements.
