Abstract
The mechanical properties of the Nylon6/clay compounded with polypropylene (PP) and polypropylene grafted with maleic anhydride (PP-g-MA) were studied. It was shown that the mechanical properties of the Nylon6/PP-g-MA/PP were little affected by the addition of 20 wt.% PP-g-MA/PP when the ratio of PP-g-MA/PP was larger than 1/4. The formulated materials had a high heat deflection temperature and all had better impact strength than the original Nylon6/clay.
The effect of polypropylene (PP) and polypropylene grafted with maleic anhydride (PP-g-MA) on the crystallization behavior of the Nylon6/clay composite was analyzed with DSC. The amount of PP-g-MA could affect the crystallization rate of the PP phase and the crystal structure of the Nylon-6/clay phase but not the crystallization rates of the Nylon-6/clay. The crystals of the PP/PP-g-MA and Nylon-6/clay were mainly a and g types, respectively.
The crystallization kinetic results derived from non-isothermal crystallization show that of Avrami exponent is about 1.01 to 2.84 for Nylon 6 phase and 0.6~1.22 for PP phase. It is indicating that the PP phaes crystallization mechanism is dominated by the athermal nucleation and growth of rol-like , the Nylon 6 phase crystallization mechanism is dominated by athermal nucleation and growth of spherulites.
