聚丙烯的共混改性研究

Study on modification of polypropylene by blending

聚丙烯作为一种通用塑料,由于其冲击强度和拉伸强度较低限制了其在工程中的应用。聚丙烯的增强增韧改性已成为使其工程化、功能化、精细化的重要手段。本文综述了聚丙烯共混增强增韧改性的研究,介绍了聚丙烯改性技术的最新进展。

Polypropylene is a extensively used plastics, but the application of PP in engineering is limited considerably by its low tensile and impact strength. It is obvious that the modification by reinforcement and toughening is an important means to improve the performance of PP relating to functionalization, fineness and engineering orientation. In this paper the modification of PP by blending is reviewed. In addition,the recent progress in modification of PP is introduced also.
