Due to their inherently high surface energy, polar end-functionalised polymers do not normally adsorb to the external surfaces of blends. However, adsorption of polar functionalities can be induced rapidly by annealing in a polar environment such as

Free-radical degradation of xyloglucan (XG) in aqueous solution initiated by 4,4′-azobis-(4-cyanopentanoic acid), potassium persulfate (KPS), hydrogen peroxide (H 2 O 2 ) and H 2 O 2 with ascorbic acid at 75–80 °C has been investigated using gel

The properties of polystyrene blends containing deuteriopolystyrene, multiply end-functionalized with C8F17 fluorocarbon groups, are strikingly analogous to those of surfactants in solution. These materials, denoted FxdPSy, where x is the number of f

An ongoing challenge in polymer science is the preparation of materials with specific surface properties which differ from that of the bulk, for example, hydrophobicity, wettability, chemical resistance, adhesion, or biocompatibility, while retaining

Dendritically fluorocarbon-functionalized poly(methyl methacrylate) (PMMA) has been explored as a robust surface-modifying additive in PMMA blends. These functionalized materials, denoted FxPMMAy, where x is the number of C8F17 fluorocarbon groups pe

The synthesis and surface properties of a 2 × C 8 F 17 fluorocarbon di-functionalized poly( d,l -lactide), “F2PLA” are described. Small fractions ∼5% w/w of F2PLA, when blended with unfunctionalized poly( d,l -lactide), “PLA”, render the s

Copper(I)-mediated living radical polymerization was used to synthesize amphiphilic block copolymers of poly(n-butyl methacrylate) [P(n-BMA)] and poly[(2-dimethylamino)ethyl methacrylate] (PDMAEMA). Functionalized bromo P(n-BMA) macroinitiators were

Frechet-type poly(arylether) dendrons with up to eight trifluoromethyl peripheral groups have been used as initiators in the copper mediated living radical polymerisation of d8-styrene, the surface adsorption behaviour and resulting properties of the

A new approach to promoting and controlling polymer surface functionalization with acidic or basic polar functional groups is demonstrated and evaluated. Blended polymer films were annealed under pH-buffered conditions, and polar end-functional group
