The concept of Initiators for Continuous Activator Regeneration (ICAR) could simplistically be considered a “reverse” ARGET ATRP as a source of free radicals is employed to slowly and continuously regenerate the very low concentration of Cu I activator which is otherwise consumed in termination reactions in ICAR ATRP. The rate of ...

2025年1月9日 · Atom transfer radical polymerization (ATRP) is a synthetic method that harnesses radical polymerization to yield well-defined polymers of controlled...

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。

2022年9月1日 · Supplementary techniques to atom transfer radical polymerization (ATRP) have been studied to reduce the concentration of catalytic complexes used, aiming at a less costly and more environmentally friendly process for synthesizing polymeric materials.

2024年12月11日 · Herein we introduce ICAR depolymerization (Figure 1C) and show that simply adding an inexpensive free radical initiator allows for efficient depolymerization of ATRP-synthesized polymethacrylates at just 120 °C. Minimization of side reactions at this temperature allows polymers to remain stable until chain-end activation to induce “on-demand ...

2014年5月16日 · The potential of Initiators for Continuous Activator Regeneration Atom Transfer Radical Polymerization (ICAR ATRP) to determine reliable Arrhenius parameters for ATRP activation/deactivation of macrospecies is illustrated using styrene as monomer and CuBr 2 /TPMA (TPMA: tris(2-pyridylmethyl)amine) as deactivator. Regression is based on an ...
