“…32 Moreover, it is a convenient indirect reporter for the molecular weight and polydispersity (PDI) of the surfaces grafted polymers provided there is a good correlation between the polymer growth from the surface and in solution. 33,34,35,36,37 In our case the sacrificial initiator EBiB is a α-halogen ester whereas the surface initiator is an amide. The latter have been reported to be prone to a higher termination rate in the initial phase of conventional ATRP resulting in higher PDIs and molecular weighs.…”

Amino-functional macroporous monoliths from polymerized high internal phase emulsion (polyHIPE) were surface modified with initiators for atom transfer radical polymerization (ATRP). The ATRP initiator groups on the polyHIPE surface were successfully used to initiate activator regeneration by electron transfer (ARGET) ATRP of (meth)acrylic monomers, such as methyl methacrylate (MMA) or tert-butyl acrylate (tBA) resulting in a dense coating of polymers on the polyHIPE surface. Addition of sacrificial initiator permitted control of the amount of polymer grafted onto the monolith surface. Subsequent removal of the tertbutyl protecting groups yielded highly functional polyHIPE-g-poly(acrylic acid). The versatility to use the high density of carboxylic acid groups for secondary reactions was demonstrated by the successful conjugation of enhanced green fluorescent protein (eGFP) and coral derived red fluorescent protein (DsRed) using EDC/sulfo-NHS chemistry, on the polymer 3D-scaffold surface. The materials and methodologies presented here are simple and robust, thus, opening new possibilities for the bioconjugation of highly porous polyHIPE for bioseparation applications.

“…The polymer coating can then enhance the resistance of wood against external stressors such as humidity, fungi, and fire. Since the first surface-initiated controlled radical polymerization (SI-CRP) from polysaccharide [182], many studies have been realized by synthesizing various polymers by SI-CRP from cellulose nanocrystals [183], fibers [184] or Whatman filter paper [185,186]. Tastet et al [137] have proceeded to the grafting of poly(PVAc, PnBA, PS, and cationic amphiphilic PS-based copolymers from raw wood fibers.…”

RAFT Polymerization of Vinyl Esters: Synthesis and Applications

This article is the first comprehensive review on the study and use of vinyl ester monomers in reversible addition fragmentation chain transfer (RAFT) polymerization. It covers all the synthetic aspects associated with the definition of precision polymers comprising poly(vinyl ester) building blocks, such as the choice of RAFT agent and reaction conditions in order to progress from simple to complex macromolecular architectures. Although vinyl acetate was by far the most studied monomer of the range, many vinyl esters have been considered in order to tune various polymer properties, in particular, solubility in supercritical carbon dioxide (scCO 2 ). A special emphasis is given to novel poly(vinyl alkylate)s with enhanced solubilities in scCO 2 , with applications as reactive stabilizers for dispersion polymerization and macromolecular surfactants for CO 2 media. Other miscellaneous uses of poly(vinyl ester)s synthesized by RAFT, for instance as a means to produce poly(vinyl alcohol) with controlled characteristics for use in the biomedical area, are also covered.

“…Heterogeneous conditions refer to situations where cellulose is not dissolved in the reaction medium so the reaction occurs at the interface between the solid and liquid phases resulting in modification only at the surface. Cellulose fibers 17,18 , membranes 19,20 and nano-whiskers 21,22 have all been modified under heterogeneous conditions. Homogeneous conditions are defined by the dissolution or, at least, by the swelling of cellulose in the reaction medium resulting in modification of the entire cellulose molecular structure.…”

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.
