| 摘 要： | 当非等物质的量比n(醇)：n(酸)=1．1：1时、自催化的己二酸／新戊二醇、己二酸／2，2，4-三甲基-1，3-戊二醇缩聚反应级数不是定值，而是与反应温度有关。低温时反应级数为2．5，高温时反应级数为3．0。

| Abstract: | Polyesterification kinetics of Adipic acid/NPG and Adipic acid/TMPD were investigated. It was found that the reaction order of self-catalyzed polyesterification is not a constant, but a function of temperature. The order of self-catalyzed polyesterification is 2. 5 in low temperatures, while 3 in high temperatures. |
