摘要：The rheology and dispersion behavior of commercial propylene-ethylene copolymer, highly filled propylene-ethylene copolymer/CaCO3 composites and highly filled propylene-ethylene copolymer/HDPE/CaCO3 composites prepared by melt-compounding were investigated. The pure propylene-ethylene copolymer exhibits pseudoplastic flow behavior obviously. The CaCO3 particles in the composites have achieved a homogeneous dispersion and the increasing shear rate has almost no influence on the dispersion behavior of CaCO3 particles. The high loading of CaCO3 particles influences the rheology behavior of propylene-ethylene copolymer slightly. For the highly filled propylene-ethylene copolymer/CaCO3 composites, the extensional viscosity only decreases slightly throughout the entire range of extension rates.
