原子转移自由基聚合 - 维基百科，自由的百科全书
网页原子转移自由基聚合 （英語： Atom-transfer radical-polymerization，簡稱 ATRP）是一种新的活性聚合反应。 与原子转移自由基加成反应一样，在原子转移自由基聚合中，二种不同的催化方法可形成碳-碳、碳-硫、碳-氮等键。 一是自由基催化，另一是金属催化。 基于历史缘由，人们现在所说的原子转移自由基聚合就是金属催化的原子转移自由基聚合。 正如其名称所指示，在原子转移自由基聚合中，自由基是聚合反应的活性种，而原子转移是活性聚 …
Atom transfer radical polymerization - Wikipedia
网页Atom transfer radical polymerization (ATRP) is an example of a reversible-deactivation radical polymerization. Like its counterpart, ATRA, or atom transfer radical addition, ATRP is a means of forming a carbon-carbon bond with a transition metal catalyst.
Atom Transfer Radical Polymerization (ATRP) - Carnegie Mellon University
网页ATRP is based on an inner sphere electron transfer process, (4) which involves a reversible homolytic (pseudo)halogen transfer between a dormant species, an added initiator or dormant propagating chain end (R-X or R-P n -X) and a transition metal complex in the lower oxidation state (Mt m /L n), resulting in the formation of propagating radicals...
