动态硫化尼龙12/丙烯酸酯橡胶热塑性弹性体的非等温结晶动力学
利用熔融共混动态硫化法制备了尼龙12/丙烯酸酯橡胶热塑性弹性体（PA 12/ACM TPV）,采用差示扫描量热仪测试了PA 12/ACM TPV和PA 12在不同降温速率下的非等温结晶行为,并分别用Ozawa和Mo方程研究了材料的非等温结晶动力学。结果表明,不同降温速率下,PA 12/ACM TPV和PA 12的结晶峰均为单峰,前者的结晶速率大于后者;Mo方程可以很好地描述PA 12/ACM TPV和PA12的非等温结晶过程,而Ozawa方程则不适合;采用Mo方程分析,PA 12/ACM TPV中橡胶相ACM的存在提高了PA 12的结晶速率。...

| Notes | Polyamide 12 / acrylic rubber（ PA 12 /ACM） thermoplastic elastomer（ TPV） was prepared by melt blending dynamic vulcanization method. The non-isothermal crystallization behaviors of the TPV and PA 12 at different cooling rates were investigated via differential scanning calorimeter,and the nonisothermal crystallization kinetics was studied by Ozawa and Mo equations. The results showed that both of PA 12 / ACM TPV and PA 12,the crystallization peaks were all unimodal,and the crystallization rate of PA 12 / ACM TPV was larger than that of PA12. The process of non-isothermal crystallization of PA 12 / ACM TPV and PA 12 were described well by Mo equation,while Ozawa equation not fitted well.Analysis with Mo equation,the crystallization rate of the PA 12 increased due to existence of rubber phase ACM in PA 12 / ACM TPV. 62-1036/TQ polyamide 12; acrylic rubber; dynamic vulcanization; thermoplastic elastomer; nonisothermal crystallization; Mo equation LIU Na, LI Chao-qin （Engineering Research Center of High Performance |
