研究了PA1010／66共聚物在液氮温度与Tm之间的松弛行为与组成的关系发现不同的松弛温度及损耗因子随共聚物组成的改变而变化的趋势不同随66含量增加，Tγ总趋势下降，Tβ总趋势增加，Tα先下降后增加；tanδ（γ）·tan-1δ（α）和tanδtan-1δ（α）先下降后增加，tanδ（α）先增大后减小。66占50％时，Tγ、Tβ极大，Tα最小；tanδ（γ）tanδ（β）、tanδ（β）·tan－1δ（α）最小，tanδ（α）最大．
The relationship between relaxation behavior and composition of PA1010 / 66 copolymer at liquid nitrogen temperature and Tm was studied. It was found that the different tendency of relaxation temperature and loss factor with the change of copolymer composition was different. With the increase of 66 content, the general trend of Tγ decreased Tα firstly decreased and then increased; tanδ (γ) · tan-1δ (α) and tanδtan-1δ (α) decreased first and then increased, tanδ (α) first increased and then decreased. Tγ and Tβ are the largest and Tα is the smallest when 50% of 66 is present; tanδ (β), tanδ (β) · tan-1δ (α) is the smallest and tanδ (α) is the largest.
