查询词典 point of transition

And the mechanism of ATRP is discussed from the view of complex-catalytic reaction. It is deduced that the active center in ATRP is not pure radical but complex active center, which maybe a complex with radical and complex ion. The structure of active center may have a "bridge"structure formed through propaganating radical and transition metal ion, and the active center exists in a"cage"generated by ligand-transition metal ion-organic halide and monomer or solvent.

论文运用基团贡献理论对一些实验现象和结果进行了讨论和分析，并结合研究结果对络合催化引发原子转移自由基聚合反应的机理进行了初步的探讨，认为：过渡金属化合物与有机配体参与的络合催化引发原子转移自由基聚合反应中，聚合反应的活性中心不是纯粹的自由基活性中心，而是与过渡金属相结合的、有着某种"笼"结构存在的复合式活性中心，同时该活性中心以自由基特性为主，同时兼具某种程度的其它活性中心特征（如阳离子和络合聚合活性中心）。
