摘要

通过固相机械化学反应器，在常温下制备了聚丙烯/聚乙烯(50/50)共混物，该共混物作为一种有效回收混合塑料废物的方法具有很大的发展潜力。系统地研究了制备的共混物的结构和性能变化。共磨后聚丙烯和聚乙烯的相尺寸明显减小，相间相容性增强。优异的冲击韧性主要归功于共混物中聚丙烯和聚乙烯相的均匀分散以及三维剪切力对PP/ pe接枝共聚物产生的增容作用。图形抽象

Influence of Solid-state Shear Milling on Structure and Mechanical Properties of Polypropylene/Polyethylene Blends

ABSTRACT A polypropylene/polyethylene (50/50) blend was prepared at ambient temperature through a solid-phase mechanochemical reactor and is shown to have potential for development as an effective way of recycling mixed plastic waste. The changes of structure and properties of the prepared blend were systematically investigated. It was found that polypropylene and polyethylene phase dimensions significantly reduced and compatibility between phases was enhanced after co-milling. The excellent impact toughness is mainly attributed to the uniform dispersion of the polypropylene and polyethylene phases in the blend and the compatibilization effect of the PP/PE-grafted copolymers produced by the three-dimensional shearing force.
