| 摘 要： | 本文研究了4-甲基丙烯酸2,2,6,6-四甲基哌啶醇酯和苯乙烯在不同温度下的自由基共聚合反应。发现在石油醚、苯和二甲基甲酰胺等溶剂中,反应温度对共聚活性的影响不同。用NMR法测定了单体与溶剂的络合常数;计算了单体与溶剂相互作用的活化能和活化熵,依此对共聚活性与温度之间的关系进行了讨论。

| Abstract: | The effects of temperature on the reactivity ratios are different in various solvents. The complex constants for monomers and solvents have been determined by NMR spectroscopy. The values of enthalpy and entropy for monomers interacting with solvents have been calculated. In accordance with these results, the dependance of monomers reactivity radio on the polymerization temperature has been discussed. |
