Photoinduced grafting

Modification of Polymer Surfaces by Photoinduced Graft Copolymerization... [Pg.168]

Photoinduced free radical graft copolymerization onto a polymer surface can be accomplished by several different techniques. The simplest method is to expose the polymer surface (P-RH) to UV light in the presence of a vinyl monomer (M). Alkyl radicals formed, e.g. due to main chain scission or other reactions at the polymer surface can then initiate graft polymerization by addition of monomer (Scheme 1). Homopolymer is also initiated (HRM-). [Pg.171]

Also we have not considered the possibility of grafting on grafted polyAM chains. If this could happen efficiently, the graft layer should have grown much thicker. Relevant to this problem, grafting onto poly(ethylene-g-maleimide) was not observed in photoinduced graft polymerization of maleimide to polyethylene... [Pg.226]

Photoinduced Grafting Reactions in Cellulose and Cellulose Derivatives... [Pg.101]

Various free radicals are generated in cellulose and cellulose derivatives by ultraviolet light, which may be capable of initiating graft copolymerization reactions with vinyl monomers. The graftability of these photoinduced free radicals in homogeneous and heterogeneous media was studied. [Pg.112]

Photoinduced graft copolymerization of cellulose derivatives especially containing carbonyl groups in the absence of a photosensitizer, has been investigated. Grafting of methyl methacrylate onto dialdehyde and dicarboxyl celluloses proceeded more easily than onto monocarboxyl cellulose. The grafting efficiency of the former two samples attained to 95-100%. [Pg.119]
