摘　　要：笔者对PA6及其与超细全硫化丙烯酸酯胶粉(以下简称UFAPR)共混体系的结晶性能及结晶动力学进行了研究,结果表明PA6及其与UFAPR共混物的晶体的生长方式相同;等速降温结晶研究结果表明,加入胶粉后,PA6的结晶度有所提高,共混物的结晶温度与纯PA6比呈升高趋势,说明UFAPR在PA6中有强的成核作用,其加入可以明显提高PA6的结晶速率和结晶温度,使晶粒分布变窄。In this paper,a study has carried out on the crystal properties and crystal dynamics of PA6?PA66 and its blends.The results show that the growing crystal way of PA6?PA66 and its blends is same.It can also be seen from the study on the cooling crystallization behavior of PA6?PA66 and its blends that the blends'w1/2 reduce,Tc and Xc rise comparing with PA6?PA66,which means the distribution of crystal grain narrowed and crystallization degree increased and it indicates rubber powdered acts as the function of heterogeneous nucleation.
