Cellulose Acetate-Graft-Poly (Methyl Methacrylate): A “Graft from” Approach of Nitroxide Mediated Radical Polymerization

Vernon Tebong Mbah*, Celli A, Cipolletti R, Sabbatini S, Stipa P

Poly (methyl methacrylate) was grafted onto cellulose acetate backbone using a “graft from” of Nitroxide Mediated Radical Polymerization (NMRP). The formation of cellulose acetate-co-poly (methyl methacrylate) using N-tert-butyl- N- (1-diethylphosphono-2,2-dimethylpropyl) (SG1)-nitroxide based macroalkoxyamine system was confirmed by FTIR and NMR analyses. The copolymer exhibited living characteristics as shown by NMR. DSC investigations showed a copolymer with a rich poly (methyl methacrylate) phase around 120°C and a rich cellulose acetate phase at around 175°C.
