MMA Polymerization of Generation of Activators by Monomer Addition (GAMA) ATRP in the Presence of ppm Amount of Fe (III) Catalyst with Phosphorus Containing Ligands |
초록 |
MMA (methyl methacrylate) polymerization via generation of activators by monomer addition (GAMA) for atom transfer radical polymerization (ATRP) has been examined in the presence of a reduced amount of catalyst with various phosphorus containing ligands. In every instance of their ATRP behavior studies, most of these systems were well controlled. Phosphorus ligands such as DPMPP (diphenyl-(2-methoxy phenyl) phosphine), DPPP (2-(diphenylphosphino) pyridine), DPPB (2-(diphenylphosphino) benzaldehyde), TPP (Triphenyl-phosphine) were applied for the Fe(III)-mediated GAMA ATRP system. Among the ligands investigated, DPMPP is the best phosphorus ligands to ppm amount of Fe-catalyzed system. The polymerizations demonstrated the features of ‘‘living’’/controlled free-radical polymerization, such as the numberaverage molecular weights increasing linearly with monomer conversion and narrow molecular weight distributions (Mw/Mn<1.3), even well if the amount of Fe (III) is as low as 10ppm. |
