| 摘 要： | 使用新型的拉伸流变挤出机制备聚丙烯马来酸酐接枝物(PP-g-MAH)。相比于传统双螺杆挤出,基于拉伸流变挤出的PP-g-MAH具有较稳定的单体接枝率(相对接枝率在6%~7%),受设备参数影响较小,单体残留率较低。拉伸流场对聚丙烯(PP)分子链降解程度较低,分别测定了拉伸流场和剪切流场下,不同转速对PP-g-MAH的接枝率/熔体流动速率(G/M)比值的影响,发现前者的产物的G/M比值随转速增加而增加,表明拉伸流场对PP分子链降解程度较低。在PP-g-MAH相对接枝率均为6%的条件下,利用拉伸流变挤出制备的PP-g-MAH的拉伸强度比双螺杆挤出产物高25%。分别和PP以不同比例共混,前者挤出的PP共混物的冲击强度比双螺杆挤出的高11%~35%。
