采用了一种可表征体系冷却收缩应力对聚合物结晶影响的动力学方法 ,研究了不同冷却速率条件下 HDPE/ Ca CO3增韧体系的基体结晶动力学行为及其与材料界面相粘结性及 Ca CO3含量之间的关系。结果表明 ,在材料缺口冲击强度较高的界面相粘结及组成条件下 ,体系熔体冷却收缩过程中所引起的界面应力的应变诱导结晶作用引起了基体晶体生长指数 n1、生长速率常数 k1及其 k1随冷却速率 a的变化率Δk1/Δa的显著增大 ;材料基体结晶动力学参数的影响因素及其变化规律与其材料缺口冲击强度的影响因素及其变化规律之间存在着良好的一致性 A kinetic method to characterize the influence of system cooling shrinkage stress on the crystallization of polymer was adopted. The matrix crystallization kinetics and the bonding with the material interface of the HDPE / CaCO3 toughened system under different cooling rates were studied. Ca CO3 content of the relationship between. The results show that the strain-induced crystallization of interfacial stress induced by the melt-shrinkage of the system caused the crystal growth index (n1), growth rate constant (k1) and crystal growth index The rate of change of k1 with the rate of change of cooling rate, Δk1 / Δa, is significantly increased. There is a good agreement between the influencing factors and the variation rules of the matrix kinetic parameters of the material matrix and the influencing factors and the changing rules of the notched impact strength
