Flow Microreactor Synthesis of Fluorine-Containing Block Copolymers

摘要: Living anionic polymerization of perfluoroalkyl methacrylates initiated by 1,1-diphenylhexyllithium was conducted without adding lithium chloride in an integrated flow microreactor system. The high degree polydispersity index (PID) control achieved at 0°C (2-(nonafluorobutyl)ethyl and 2-(tridecafluorohexyl)ethyl methacrylates) or −40°C (2,2,2-trifluoroethyl methacrylate). subsequent reaction a reactive polymer chain end with alkyl tert-butyl acrylate led to the formation fluorine-containing block copolymers narrow PDI.
