摘　　要：尼龙-1010是我国独创的工程塑料品种,已被较广泛地应用于精密机械零件、仪表制造、家用电器、航空等方面。有关尼龙-1010的基础研究大多在我国学者中间进行,由于在实际加工生产过程中,如通常的融熔纺丝、注射、模压等工艺均是在非等温条件下进行,有关它的非等温结晶动力学尚未见报道,本文用几种理论方法对尼龙-1010的非等温结晶动力学过程进行研究。The kinetics of non-isothermal crystallization of Nylon-1010 has been investigated by using differential scanning calorimetry (DSC),DSC curves were obtained under cooling rates (R):2. 5, 5.10,20, 40K/min. Applying Mandelkern and Ziabicki Theories, the values of the Zc and Gc-the kinetic crystallizability have been determined. The exponents of Avrami obtained in this work decrease with the increase in cooling rate and then remain at a definite value. The experimental results analysed show disagreements with the Ozawa equation.
