grafting reactive extrusion

基本解释

Melt grafting modification of polypropylene were introduced in this paper, including its formation, mechanism and reactive extrusion to achieve melt grafting.
系统简介了聚丙烯熔融接枝体系的组成、机理及实现熔融接枝的反应挤出技术。
The mixing performance of different screw configurations of a co-rotating twin screw extruder and the grafting reactive extrusion of PE-LDg-MAH were investigated.
研究了不同螺杆构型的混合性能以及低密度聚乙烯熔融接枝马来酸酐的过程，探讨了不同螺杆构型的混合性能与接枝反应接枝率的关系。
The melt grafting of maleic anhydride (MAH) onto PE/PP was carried out via reactive extrusion. The effects of the contents of MAH, initiator (DCP) and PP on the system were studied.
研究了聚乙烯（ PE）和聚丙烯（ PP）共混物接枝马来酸酐（MAH）时，引发剂（ DCP）、接枝单体（MAH）和PP用量对接枝率的影响。

接枝反应挤出
Experiment results agreed with the simulation results, so developing a novel screw element or selecting the screw configurations for grafting reactive extrusion just need to analyze the characteristic of the screw element.
实验所得的各螺杆元件的混合性能与数值模拟结果一致，说明本文所用的数值模拟分析方法可以用于选择熔融接枝反应挤出所需的螺杆构型组合及新型螺杆元件的设计与分析。
