摘要: 以两类典型的缩聚反应为例,研究了缩聚反应的统计理论和反应动力学理论之间的内在联系,给出反应程度与平衡反应动力学常数以及聚合反应自由能之间的关系.在此基础上,借助于聚合反应平衡常数使一些平均高分子物理量的表征得以简化.从热力学角度进一步研究了温度和压力等热力学量对反应体系的影响.

Abstract: By the investigations of two types of representative polycondensations from statistical theory and dynamics,the relationship between the dynamics and statistics of the system under consideration is pointed out.Based on this,we obtain the explicit relationship between the conversions and equilibrium dynamical constant and reaction free energy,by which the characterization of the average polymer physical quantities can further be simplified.Moreover,the influences of temperature and pressure on the polymerization process are discussed.

Key words: Polycondensations, Statistical mechanics, Equilibrium reaction dynamics
