摘要: Abstract Living anionic polymerization of alkyl methacrylates initiated by 1,1-diphenylhexyllithium was conducted in a flow microreactor system. A high level molecular-weight distribution control achieved under easily accessible conditions, such as at −28 °C (MMA: Mw/Mn = 1.16), 0 °C (BuMA: Mw/Mn = 1.24) and 24 °C (Bu t MA: Mw/Mn = 1.12). The molecular weight (Mn) increased with an increase the monomer/initiator ratio. subsequent reaction reactive polymer chain end second methacrylate integrated micoreactor systems led to formation block copolymer having narrow distribution.
