动态硫化PA12/ACM TPV等温结晶动力学研究

利用熔融共混动态硫化的方法制备尼龙12（PA12）/丙烯酸酯橡胶（ACM）热塑性弹性体（TPV），并研究PA12/ACM TPV和PA12的等温结晶行为。结果表明：PA12/ACM TPV和PA12的等温结晶行为均符合Avrami方程；在相同结晶温度下，PA12/ACM TPV的结晶速率比PA12大；结晶行为对温度依赖性较大。;The nylon 12（PA12）/acrylate rubber（ACM）thermoplastic vulcanizate（TPV）was prepared by melt blending dynamic vulcanization method，and the isothermal crystallization behaviors of PA12/ACM TPV and PA12 were investigated. The results showed that，Avrami equation was satisfied in describing the crystallization behavior of the two samples，the crystallization rate of PA12/ACM TPV was faster than that of PA12 at the same crystallization temperature. The crystallization behavoir relied on crystallization temperature
