| 摘 要： | PVC/CPE blend modified by rigid particles has good combined properties. In this paper, the effeCts of rigid particles (PMMA. PS. CaCO,) on the rheological behavior of PVC/ CPE systems were studied. The results showed that the apparent viscosity (aha) were decreased, extrusion surface smooth and Newtonian fluidity were slightly improved by filling a little amount of rigid ploymers (PS. PMMA) to PVC/CPE blends. The fluid activition energy (E,). Newtonian fluidity. extrusion surface smooth and ba of PVC/CPE blends were increased by filling CaCO3 and die swelling ratio was decreased.The newtonian fluidity. En and ηa of PVC/CPE/CaCO3 blends can be decreased by filling rigid polymers,and good extrusion surface smooth and low die swelling ratio unchanged.
