Continuous atom transfer radical block copolymerization of methacrylates

Abstract A column reactor packed with silica‐gel‐supported copper bromide (CuBr)–hexamethyltriethylenetetramine (HMTETA) was developed for the continuous‐transition–metal‐mediated living/controlled radical polymerization [atom transfer radical polymerization (ATRP)] for homo‐ and block copolymerization of methyl methacrylate (MMA). The reactor showed good stability (>100 h) in both catalyst activity and molecular weight of the poly(methyl …
