    Notes: The rheological properties and viscoelasticity of PAN/DMSO solutions were studied bymeans of revolving rheometer under the scan modes of steady shear rate and dynamic frequency.The effects of shear rate and temperature of PAN/DMSO solution on its Non-Newtonian viscousindex, zero shear viscosity, activation energy of viscous flow and modulus of the solutions werestudied. It was found that PAN/DMSO solution is a kind of pseudoplastic fluid. And the moretemperature of solution, the less Non-Newtonian viscous index at steady experiment curve, the lessthe loss modulus and storage modulus of solution at dynamics experiment curve. In addition, theliquidity and spinnability of the solution also increased when the temperature went up

    Ternary Polypropylene/Polyolefin Elastomer/Attapulgite Composites (2006)

    Notes: Modification of polypropylene (PP) by the addition of polyolefin elastomer (POE) andattapulgite (AT) has been investigated. The result have shown that the addition of POE and AT gavePP excellent mechanical properties of improved impact strength and comparable stiffness. Thebonding between AT and the matrix was enhanced with the addition of dispersant EBS. AT was aneffective nucleating agent for PP crystallization, and finer and more homogeneous spherulites of PPwas obtained. In this study, the toughening mechanism of the composites was also discussed
