| 英文摘要: |
| This paper describes the application of atom transferring radical polymerization(ATRP) of methyl methacrylate(MMA) at ambient temperature(30 ℃) by using ethyl 2-bromoisobutyrate(EBiB)/CuBr/Bpy as initiating system and cyclohexanone as solvent.The polymerizations of MMA conform to first order kinetic behavior,and the molecular weight linearly increases with the monomer conversion.Furthermore the polydispersity indexes(PDI) remain in low values(1.07~1.15).The polymerization rate increases as increasing the reaction temperature.Obtained polymers have been successfully conducted chain extension by using polymer as a macro-initiator and resulted polymers were characterized by NMR,GPC. |
