摘要
用动态力学方法研究发现尼龙１０１０／６ 共聚物在测试温度范围内有三个松弛峰，分别为α、β、γ松弛峰。在温度谱中，１ ＃ 、２ ＃ 、６ ＃ 样品的α松弛峰较宽，３ ＃ 、４ ＃ 、５ ＃ 样品的α松弛峰较窄，各样品的β、γ松弛峰峰形较小，相差不大。其中２ ＃ 样品的α松弛峰最高，动态模量最大；４ ＃ 样品的α松弛峰最低，模量最小。
The dynamic mechanical property of 1010/6 copolyamides was studied by DDV test. It′s found that there are three relaxations between the temperature of liquid nitrogen and melting point: α、β、γ relaxation. Introduction of 6 or 1010 monomer into nylon 1010 or nylon 6 resultes in decreasing of [E] and E″. But the copolyamide with nylon 6 67.7 mol% attains minima of [E] and E″.
