(a) The mechanism of transition metal-catalyzed ATRP. (b) Proposed mechanism of ARGET ATRP in the presence of limited amounts of air [31]. Typical setup for grafting polymer chains from silicon wafers using ARGET ATRP with limited air (c) in a large jar and (d) in a sample vial. (e) Illustration of procedures for surface-initiated ARGET ATRP with limited air. (f) Relationship between the grafted poly(butyl acrylate) (PBA) brush thickness measured in air by ellipsometry and Mn of free PBA polymers. In this example, it was demonstrated that polymers could grow with or without stirring. It was also shown that the polymerization could be stopped and re-started with continued growth of PBA chains, or extension of the chains by polystyrene.
