摘要： 尼龙1010的晶体结构属三斜晶系[1].作者[2]最近导出了X射线衍射法(WAXD)测定尼龙1010结晶度的公式,进而考查了等温结晶时结晶温度TC对结晶度XC、晶粒尺寸L100和氢键面相对衍射强度R的影响.发现XC和L100均随TC升高而增大,达196℃后又减小;而R与TC的关系则相反,呈线性降低.结晶速率快有利于分子链在垂直于氢键面的(100)晶面生长,但R值却降低了[3].本文利用WAXD考查了尼龙1010不同骤冷退火条件样品的晶体结构.

Abstract: The present paper covers the relationships between the crystallinity Xc, crystalline size L100, and relative diffraction strength of plane parallel to hydrogen-bonds'sheets R, with the quenched conditions and annealed temperature Ta for the quenched and annealed samples of nylon 1010 studied by WAXD.For the samples that were quenched at room temperature and then annealed (RT), if Ta <196℃ , Xc and L100 are increased with the raising of Ta, Rdecreased ; if Ta >196℃, the relations are turned back.For quenched in liquid N2 and then annealed samples (LN) , Xc and Rare increased with Ta raising, but L100 has not any regularity.At the same time Ta, Xc and L100 of RT samples are larger than those of LN samples, but Rand the increment of crystallinity of LN in the annealed process are larger than those of RT.
