摘　　要：采用浓度-时间比法研究端羟基聚丁二烯(HTPB)/N100反应动力学,利用Matlab软件计算得到反应级数和不同温度下反应速率常数,考察了反应速率变化对催化剂用量的依赖关系,并对过程中粘度与时间的变化关系进行研究。结果表明:HTPB/N100反应符合一级反应规律,活化能Ea=70.57 kJ·mol-1;反应速率常数与催化剂用量成正相关;建立反应体系的粘度-时间指数模型能准确反映过程中两者间的关系。Hydroxyl-terminated polybutadiene（HTPB）/N100 reaction kinetics was investigated by method of the ratio of concentration and time.Matlab software was applied to calculate the reaction order and rate constant under different temperatures.The effects of various additions of catalyst on reaction rate,and the relationship between time and viscosity for HTPB/N100 reaction were studied.Results show that the reaction of HTPB/N100 belongs to the first order reaction,and activation energy is 70.57 kJ·mol-1.With the increasing of catalyst proportion,the reaction rate constants increase,and the established exponential model for time-dependent of reaction system reveals their quantitative relationship.
