Atom-Transfer Radical-Polymerization (ATRP)

Reaction [1]:

Mechanism [2]:

Specific example [3]:

Highlights and Significance:

  1. ATRP is a controlled radical process for polymerization of styrenic, acrylic, and methacrylic monomers. [4]
  2. The radical termination reaction is not fast because the concentration of active radicals is low. [5]
  3. External visible light stimulation ATRP has a high responding speed and excellent functional group tolerance. [6]
