Crystal Structure of the Quenched and Annealed Samples of Nylon 1010

Abstract

Abstract: The present paper covers the relationships between the crystallinity X_c, crystalline size L₁₀₀, and relative diffraction strength of plane parallel to hydrogen-bonds'sheets R, with the quenched conditions and annealed temperature T_a 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 T_a <196℃ , X_c and L₁₀₀ are increased with the raising of T_a, Rdecreased ; if T_a >196℃, the relations are turned back.For quenched in liquid N₂ and then annealed samples (LN) , X_c and Rare increased with T_a raising, but L₁₀₀ has not any regularity.At the same time T_a, X_c 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.
