Measurement of the rheological properties of polymer melts with slit rheometer. III. Two‐phase systems—high‐impact polystyrene and ABS resin

摘要

AbstractMeasurements were made of the rheological properties of commercially available rubber‐reinforced two‐phase polymer systems. The polymers chosen for study were two high‐impact polystyrenes (Union Carbide Corp., TGDB9500 and TGDB2100) and an acrylonitrile–butadiene–styrene (ABS) resin (Monsanto Co., Lustran I240 Natural). For the study, a slit rheometer was used, which was described in part I of this series. The present paper, the third of this series, clearly demonstrates the usefulness of the slit rheometer for characterizing polymer systems of industrial importance by means of their viscous and elastic properties in the mol
