【摘要】 对熔纺的系列聚苯硫醚（ＰＰＳ）拉伸纤维的升温ＤＳＣ谱图冷结晶部分进行了非等温结晶动力学研究，发现取向ＰＰＳ纤维的结晶过程可近似用一级动力学模型模拟。该系列试样随着拉伸倍数的增大，低温结晶速率增大，而高温结晶速率减小。更多还原

【Abstract】 The cold crystallization of the melt spun poly(phenylene sulfide) fibers in hot drawing process was studied with the non isothermal crystallization kinetics method by DSC patterns. The results showed that their crystallization kinetics could be approximatively described by the first order kinetic model, and the crystal rates of the series samples increased in lower temperature range and decreased in higher temperature range with increasing draw ratio .更多还原
