Abstract: The kinetics of nylon-1010 polycondensation at earlier stage in an open system was studied. The melt polycondensation process in an open system was feasible since the volatibility of 1,10-decanediamine was low enough in the process.The kinetics was characterized by the pesudo-nonreversible reaction of the second order. The activation energy was measured to be 82.7 kJ•mol^-1.It was much faster in comparison with the polycondensation of nylon-66 in a closed system.

摘要： 研究了尼龙-1010盐敞开系统熔融缩聚的前期动力学.结果表明，癸二胺挥发程度低，敞开系统熔融缩聚工艺可行，其动力学符合拟不可逆二级反应机理，活化能为82.7 kJ•mol^-1，尼龙-1010缩聚速率远比密闭体系的尼龙-66快.
