原子转移自由基聚合( ATRP，Atomic transfer radical polymerization) 是可逆失活自由基聚合的一个例子。 与其对应物ATRA或原子转移自由基加成一样，ATRP 是一种利用 过渡金属催化剂 形成碳碳键的方法。

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. Polymerization from this method is called atom transfer radical addition polymerization (ATRAP

AGET ATRP initiation systems are similar to SR&NI ATRP in that it starts with (pseudo)alkyl halides as initiators and transition metal complexes in their oxidatively stable state (e.g., Cu II Br 2 /ligand) as catalyst precursors allowing the most active catalyst complexes to be added to the reaction prior to in-situ activation.

2022年11月9日 · Atom transfer radical polymerization (ATRP) is one of the most powerful methods to prepare well-defined (co)polymers. Cu-catalyzed ATRP methods are most commonly used because of the excellent control and tunable catalytic activities via ligand functionalization.

A commonly used chemical reducing agent, ascorbic acid, can be used in both AGET and ARGET ATRP. SR&NI and ICAR ATRP generally differ in the amount of catalyst used and in the rate of catalyst reduction.

2024年5月15日 · Atom transfer radical polymerization (ATRP) is one of the most often used controlled radical polymerization techniques. It employs very small amounts (ppm) of Cu complexes in the presence of various chemical reducing agents but also external stimuli such as light, electrical current or mechanical forces.
