| 摘 要： | 根据尼龙6固相聚合反应机理,建立了由可逆化学反应和小分子扩散共间控制的尼龙6固相聚合动力学模型,并确定了其动力学和热力学参数。通过计算机模拟实验表明,聚合反应温度越高,预聚体尺寸越小,预聚体初始相对分子质量越高,越有利于固相增粘反应,有利于固相聚合尼龙6相对分子质量的增加。

| Abstract: | The kinetic model for solid-state polymerization of nylon 6 which was controlled by reversible reaction and small molecule diffusion was established based on the mechanism of nylon 6 solid-state polymerization. The kinetic and thermodynamic parameters were decided. The results obtained from the computer simulation experiment showed that the high polymerization temperature , the small size and the high initial molecular weight of prepolymers were helpful to the growth of molecular weight of nylon 6 during the solid-state polymerization. |
