Abstract

Abstract: This paper applies ARGET(activators regenerated by electron transfer)ATRP(atom transfer radical polymerization)to graft methyl methacrylate(MMA)and sodium methacrylate(MAA-Na)from microcrystalline cellulose, respectively. The grafted substrates were evaluated with FT-IR and SEM, suggesting that polymethylmethacrylate(PMMA)was successfully grafted from the surface of microcrystalline cellulose. The free polymer PMMA was characterized by GPC, showing that the molecular weight distribution was narrow(M_w/M_n=1.12)and sufficient control was achieved when grafting monomers from the cellulose substrates via ARGET ATRP. Furthermore, the influence of time on grafting microcrystalline cellulose with MAA-Na through ARGET ATRP was investigated. The results revealed that monomer conversion increased with the reaction time, corroborating that ARGET ATRP can get good control on the length of the side chains grafted from the substrates. The distribution and the length of polymer chains graftod from microcrgstalline celluloso can be well controlled by ARGET ATRP.
