利用ＤＳＣ法研究了拉伸对尼龙１０１０熔融与结晶的影响．结果表明，伸长倍数（λ）较低时，ＤＳＣ曲线上只有一个溶融峰；λ较高时出现双熔融峰．λ≤１．５时，结晶度（Ｗｃ）随λ的增大而减小，λ＞１．５时，Ｗｃ随λ的增大而增大，λ≤２．５时Ｗｃ随拉伸温度（Ｔｄ）的升高而降低，λ≥３时，Ｗｃ与Ｔｄ基本无关或略有上升．拉伸速度ｖ＝１０ｍｍ／ｍｉｎ，λ≈２．５和ｖ＝１００ｍｍ／ｍｉｎ，λ≈３．３时，熔程（ΔＴ）有一极大值，ｖ＝１０ｍｍ／ｍｉｎ时，ΔＴ与Ｔｄ无关，ｖ＝１００ｍｍ／ｍｉｎ，Ｔｄ≈８０℃时，ΔＴ有一极大值．熔点Ｔｍ随λ的增大略有下降，而与Ｔｄ和ｖ无关．
The effect of stretching on the melting and crystallization of nylon 1010 was studied by DSC. The results show that there is only one melting peak on the DSC curve at lower elongation (λ), and double melting peak at λ higher. When λ≤1.5, the crystallinity (Wc) decreases with the increase of λ. When λ> 1.5, Wc increases with the increase of λ, while λc≤2.5, Wc changes with the stretching temperature Td) increased and decreased, λ ≥ 3, Wc and Td basically unrelated or slightly increased. Tensile velocities v = 10 mm / min, λ≈2.5 and v = 100 mm / min and λ≈3.3 have a maximum melting range (ΔT) and ΔT is independent of Td at v = 10 mm / When v = 100 mm / min and Td≈80 ° C, ΔT has a maximum value. The melting point Tm decreases slightly with the increase of λ, but has nothing to do with Td and v.
