Abstract
For increasing the toughness of polypropylene and expanding its applications,the modification mechanism polypropylene is discussed in this paper, and the inorganic particles (calcium carbonate)and organic plastic materials (polyethylene St) are used to modify the polypropylene in this article.The characterization of the polypropylene modified by calcium carbonate and St-modified shows much better toughness and mechanical strength than the pure polypropylene.
