2022年7月26日 · This Perspective highlights fundamental advances in the design of ATRP reactions and catalysts, focusing on the crucial role that mechanistic studies play in understanding, rationalizing, and predicting polymerization outcomes.

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。

2002年1月12日 · Patterned films of a low-polydispersity polymer densely end-grafted on a silicon substrate were fabricated for the first time by the combined use of the Langmuir−Blodgett (LB) and the surface-initiated atom transfer radical polymerization (ATRP) techniques: a blend monolayer of 2-(4-chlorosulfonylphenyl)ethyltrimethoxysilane (CTS: ATRP ...

2016年2月24日 · This focused review describes how surface properties can be manipulated by combining surface-initiated atom transfer radical polymerization (SI ATRP) and the very-large-scale integration (VLSI...

2022年11月9日 · ATRP involves a catalytic process using reversibly exchanged activators (typically Cu I L +, where L = ligand) and deactivators (typically X-Cu II L +, where X = halogen atoms, e.g., Cl or Br) (Scheme 2, top). Cu complexes are the most common and thoroughly-studied ATRP catalysts.

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.

2016年3月31日 · Atom transfer radical polymerization (ATRP) has become one of the most implemented methods for polymer synthesis, owing to impressive control over polymer composition and associated properties. However, contamination of the polymer by the metal catalyst remains a major limitation.

2017年4月3日 · In copper-catalyzed ATRP, the dormant halogen-capped polymer chains react with a Cu (I) species (the activator) to liberate a carbon-centered radical capable of propagating with monomer. Growth of polymer chains proceeds until a Cu (II) species (the deactivator) reinstalls the halogen.

High stability and appropriate K ATRP (ATRP equilibrium constant) were found crucial for the catalyst working under high dilution or in coordinating solvents/monomers. This provides guidance for further design of highly active ATRP catalysts.

Atom-transfer radical-polymerization (ATRP) is a reaction where carbon–carbon bond formations occur via a transition metal catalyst e.g. copper complexes. From: Biotechnology Advances, 2013
