摘　　要：对乙烯 辛烯共聚物(EOC)和CaCO3两种增韧剂分别和协同增韧增强聚丙烯复合材料体系的形态结构与性能的关系进行了系统的研究,验证了EOC和CaCO3增韧PP的机理符合Wu氏逾渗理论,揭示了PP/EOC/CaCO3体系发生脆韧转变的基本条件是L≤Lc(≈0.095μm),首次成功实现了对PP/EOC/CaCO3体系脆韧转变行为的定量化研究。The relationships between the structure and properties of polypropylene composites toughened and reinforced by EOC and CaCO3 respectively or together were studied systematically.The toughening mechanisms of PP/EOC and PP/CaCO3 systems are proved to agree well with Wu's percolation theory.It is revealed that the essential condition occurring brittletough transition in PP/EOC/CaCO3 ternary system is L≤ Lc(≈0095μm).The quantitative study of PP/EOC/CaCO3 composite is successfully realized.
