英文摘要	In this work, rheological properties of a novel fabricated random high impact polypropylene-based copolymer, PBE, which possessed excellent properties of transparency and impact resistance, were studied. The studying included shearing stress, apparent shearing viscosity, viscous flow activation energy, extrudate swelling ratio, melt strength and melt extrusion morphology et al. The study was based on a capillary rheometer using RPB and RPE; both are used extensively at present, and the processing technologies are mature, as control. Based on the study, the following results arrived. Firstly, PBE is a pseudoplastic fluid and the processing methods used for RPE and RPB are fully applicable to PBE. Secondly, PBE presented the highest shearing sensitivity among above-adopted samples, and temperature and shearing rate showed the greatest influence on the rheological properties of PBE. Thirdly, the melt strength of PBE was significantly lower than that of RPB and RPE, but greatly varied with temperature, which indicated that injection molding was the most suitable for PBE. Finally, the study was also found that at a given shearing rate, the extruded swelling ratio of PBE was the smallest, which indicated this material has the best dimensional stability of the product.
