| 摘 要： | 基于传统的链式聚合和逐步聚合二种高分子链增长过程,提出了再活化链式聚合。按此聚合机理,高分子的链增长是通过将一个非活性或睡眠状态的链(Mm)重新活化为活性种(Mm*),活性种再和一个单体(M)反应,生成一个较大分子量的休眠产物(Mm 1)来实现的。再活化链式聚合主要例子包括苯胺和或许其它芳香族单体的氧化聚合,活性自由基聚合,以及核酸和蛋白质合成中的生物聚合。

| Abstract: | A new general mechanism of polymerization,reactivation chain polymerization,has been proposed based on the classical chain and step polymerization mechanisms.According the present mechanism,the polymer chain propagation is accomplished by reactivating a nonreactive or dormant chain(M_m) to a reactive species(M~*_m),which reacts with a monomer(M),leading to formation of a dormant product with higher molecular weight(M_(m 1)).Major examples of the reactivation chain polymerization include the oxidative polymerization of aniline and probably other aromatic monomers,living radical polymerization,and biological polymerization for the synthesis of nucleic acids and proteins. |
