| Abstract: | Nylon6/ABS(acrylonitrile butadiene styrene) /ABS-g-MAH(maleic anhydride) alloys with different ratio of compatibilizer and ABS-g-MAH were prepared using a twin-screw extruder.The melting behavior and isothermal crystallization kinetics were investigated using differential scanning calorimetry(DSC).The results indicate that two molten peaks combine into one with the rise of the crystallization temperature(to 194 ℃);Crystallization time becomes shorter and the crystallization rate increases with the addition of compatibilizer.The analysis of the crystallization kinetics demonstrates that the Avrami equation well describes the isothermal crystallization process of the primary stage,showing good linear relationship between lg{-ln[1-X(t)]} and lgt.The spherulites growth kinetics parameters were examined,n is between 2.00 and 2.99,the experimental results confirm that the presence of ABS-g-MAH increases the crystallization rate of Nylon 6. |
