Abstract: The double bond selective anionic polymerization of 2, 3-epoxy propyl methacrylate has been carried out.It is found that the dominant by-reaction occurred in initiation process at lower temperature(<-40℃),not in propagating period,because of the interaction between initiator and epoxy group of monomer.This by-reaction can be restricted by the use of initiator with lower reactivity.On the other hand,higher polymerization temperature(>-20℃)will result in the cross-linking reaction, so it is difficult to control the double bond selective polymerization.GPC.¹HNMR and FTIR measurements indicate that a soluble functional polymer with an epoxy group in each repeating unit and monodispersity (M_w/M_n<1.10) has been prepared by proceeding the polymerization with 1,1'-diphenylhexyllithium in THF at lower temperature.
