一、前言近年来,自由基聚合反应中的磁场效应逐渐引起人们的兴趣和重视。包含自由基对的聚合反应的能力及产物性质如何受外磁场的影响,是当今聚合物科学的新课题。对于聚合反应,其反应速率不仅取决于能量因素,同时也取决于熵因素。由阿累尼乌斯公式可知,速率常数表达式如下: I. Introduction In recent years, the magnetic field effect in free radical polymerization gradually arouses people’s interest and attention. The ability to include radical-based polymerization and how the product’s properties are affected by external magnetic fields are new topics in polymer science today. For polymerization, the reaction rate depends not only on the energy factor, but also on the entropy factor. The Arrhenius equation shows that the rate constant is expressed as follows:
