| 摘 要： | 研究了聚丙烯接枝超支化聚（酰胺酯）（PPHBP）／PP／聚氯乙烯（PVC）共混体系的流变行为。讨论了PP-HBP用煮对PP／PVC共混体系流变行为的影响。结果表明，当PP／PVC共混体系中加入PPHBP不大于5份时，PP／PVC／PPHBP共混体系的表观粘度大于PP／PVc共混体系的；当加入PP—HBP大于5份时，PP／PVC／PP-HBP共混体系的表观粘度小于PP／PVC共混体系的；随着温度升高，PP／PVC和PP／PVC／PP—HBP共混体系表观粘度减小。

| Abstract: | The effect of polypropylene(PP) grafted with hyperbranched poly(amide-ester)(PP-HBP) on rheologic behavior of polypropylene/poly(vinyl chloride)(PP/PVC) was studied.The influences of the amount of PP-HBP on rheologic behavior of PP/PVC blend were discussed.The results showed the apparent viscosity of PP/PVC/PP-HBP blend was higher than that of PP/PVC blend when the amount of PP-HBP was(5 phr) or less than(5 phr,) whereas the apparent viscosity of the PP/PVC/PP-HBP blend was lower than that of PP/PVC blend when the amount of PPHBP was more than 5 phr.The apparent viscosity of PP/PVC and PP/PVC/PP-HBP blends decreased with increase of temperature. |
