“…In the 13 C NMR spectrum of MCC-BiB, peaks for the methyl (a), quaternary (b and e) carbons of BiB groups and methylene carbon (c) of MCC are observed at 30.8, 58.2, 171.7, and 66.1 ppm respectively. These NMR spectra were in agreement with the data reported by Meng et al [3].…”

“…This was due to more availability of catalyst molecules to convert more macro-initiator to be radical species which initiate polymerization reaction. The mole ratio range of 1.0 to 1.5 indicated the total number of bromide bonded in MCC-BIB, as commonly reported [3,12]. In addition, the excess amount of catalyst was able to lower the copolymer recovery.…”

“…Atom transfer radical polymerization (ATRP) which is one of modification methods has been extensively studied for graft copolymerization of vinyl monomers onto cellulose and cellulose derivative [3]. This method can produce copolymer with controlled graft density and length as well as low polydispersity index [4].…”

Abstract. The synthesis of a cationic cellulose copolymer from cellulose macro-initiator (MCC-BiB) and quaternary compound monomer (METMA) via atom transfer radical polymerization (ATRP) was studied. By using dimethylformamide (DMF), the optimum condition for successful synthesis was at the mole ratio of MCC-BIB: Catalyst:METMA = 1:1:26. The highest copolymer recovery was 93.2 % for 6 h and at 40 o C. The copolymer was insoluble in weak polar solvents such as THF and DMF but soluble in methanol and water. The chemistry of cellulose copolymer was confirmed by the FTIR and TGA in which the METMA monomer was used as a reference. The absence of C=C bond in the CiB-g-METMA spectrum indicated that graft copolymerization occurred.

“…However, a low temperature (50 °C) reduced the graft ratio, and thus a compromise between reaction time, temperature and concentration was required to achieve a 38% monomer conversion, a Ɖ M and graft ratio of 1.65. Compared to the work of Meng et al 42 and…”

The macro-initiator Br-Cell was prepared from bromoisobutyryl bromide under homogeneous conditions using 1-allyl-3-methyl-imidazolium chloride ([AMIM]Cl) and the influence of the reaction conditions on the DS were evaluated.…”

In this comprehensive review, we report on the preparation of graft-copolymers of cellulose and cellulose derivatives using atom transfer radical polymerization (ATRP) under homogeneous conditions. The review is divided into four sections according to the cellulosic material that is graft-copolymerised; i) cellulose, ii) ethyl cellulose, iii) hydroxypropyl cellulose and iv) other cellulose derivatives. In each section, the grafted synthetic polymers are described as well as the methods used for ATRP macro-initiator formation and graftcopolymerisation. The physical properties of the graft-copolymers including their selfassembly in solution into nanostructures and their stimuli responsive behaviour are described.Potential applications of the self-assembled graft copolymers in areas such as nanocontainers for drug delivery are outlined.
