摘　要：纳米碳酸钙和三元乙丙橡胶接枝马来酸酐对聚丙烯具有显著的协同增韧作用,可能是因为纳米碳酸钙和三元乙丙橡胶接枝马来酸酐之间发生物理化学作用,形成一种新的核壳结构(硬核软壳),与一般的核壳增韧剂(硬壳软核) 完全不同 .

　　A traditional way to toughen the plastic materials is to blend them with a kind of suitable rubber or thermoplastic elastomers[1～ 2].This way is capable of raising their impact strength in a large scale,nevertheless,as a severe side effect,their stiffness and strength decreases greatly.An alternative way is to add a certain kind of organic[3] or inorganic[4] rigid particles into the objective plastics.As a result,their toughness,stiffness,and strength might be raised simulatanously,but not very effectively at all.In this article,we have developed a novel method to engineer a general polypropylene(PP),where nano calcium carbonate(nm-CaCO3) and ethylene-propylene-diene copolymer grafted maleic anhydride(EPDM-g-MAH) synergistically toughens PP multitudinously,while its modulus and strength is almost unchanged.
