“…"Grafting from" is commonly used, where synthetic polymer chains are grown from sites on the cellulose backbone. The cellulose backbone can be activated via a range of processes including single electron transfer 14 , hydrogen abstraction 15,16 , irradiation 17,18 or other methods 8,12,19 . From the resulting macro-initiator sites, polymer chains can be grown producing the graft copolymer.…”

“…Furthermore, the aggregated structure at pH above 6.9 prolonged the drug release over time compared to the structure generated at pH 6.6. PDMAEMA 23 -g-PCL 30 -g-EC was also analyzed using DSC and WAXD and it proved to be amorphous because the EC and especially the PDMEAMA chains disturbed the order of the PCL.…”

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.

“…Recently, PVP has been introduced on to cellulosic materials via NVP graftcopolymerization in order to combine the properties of PVP and cellulose. The resulting graft copolymers were shown to have improved metal sorption, 20 swelling, 21 thermal stability, 22 biodegradability resistance, 23 and solubility. 24 The functionalization of HEC via its three available hydroxyl groups could lead to the development of novel materials with the properties of synthetic polymers but which are produced, in large part, from a renewable feedstock.…”

Lactam groups were introduced onto the backbone of hydroxyethyl cellulose (HEC) to modify properties, such as solubility in organic solvents and solution viscosity and to introduce possible antibacterial activity. Functionalization was achieved using 1-(hydroxymethyl)-2-pyrrolidinone (HMP), and the functionalization reactions were investigated using NMR spectroscopy. The covalent attachment between HEC and HMP was confirmed using 1 H-13 C correlated NMR experiments. Degrees of functionalization were calculated using integrated 13 C NMR spectra, with values of up to 0.9 being demonstrated on the primary alcohol functionality of HEC. The functionalized HECs showed markedly different properties to unfunctionalized HEC, including the ability to swell considerably in water. Functionalized HEC displayed increased thermal stability and reduced solution viscosity compared with unfunctionalized HEC. Moreover, functionalization altered the bacterial adhesion characteristics compared with unfunctionalized HEC.
