摘要
采用差示扫描量热法研究了不同配比的聚酰胺6/丙烯腈-丁二烯-苯乙烯共聚物(PA6/ABS)共混物的非等温结晶过程,同时研究了冷却速率对PA6/ABS(80/20)共混物结晶行为的影响,对其数据分别采用Jeziorny法和Mo法进行处理。结果表明,共混物中ABS含量由0提高到30%时,Avrami指数n从4.55增大至7.04,结晶峰温由174.2℃提高到183.3℃;随着冷却速率的增大,PA6/ABS(80/20)共混物结晶度降低,结晶峰值温度降低,半结晶时间减小。
The non-isothermal crystallization behavior of PA6/ABS blends were investigated using differential scanning calorimetry(DSC). The DSC data was analyzed with Jeziorny and Mo methods. With increasing ABS content, the Avrami index n increased from 4.55 to 7.04 and the crystallization peak temperature increased from 174.2 ℃ to 183.3℃. With increasing cooling rate, the crystallinity, crystallization temperature, and half-crystallization time decreased.
