Cellulose Graft Copolymers: Synthesis, Properties, and Applications
Grafting of vinyl monomers onto cellulose is an important tool for the modification of cellulose. Depending on the monomer grafted onto cellulose, it gains new properties. The grafting can be performed in heterogeneous or homogeneous medium. In the grafting performed in heterogeneous medium, the reaction is carried out in aqueous medium using a suitable initiator. As initiator, the radiation or...
متن کاملSynthesis of Cellulose-graft-poly(methyl Methacrylate) via Homogeneous Atrp
Cellulose-graft-poly(methylmethacrylate) (cellulose-g-PMMA) copolymers were prepared by homogeneous atom transfer radical polymerization (ATRP) under mild conditions, in an attempt to develop an efficient way to modify the surface of cellulose. A cellulose macro-initiator was successfully synthesized by direct homogeneous acylation of cellulose with 2-bromopropionyl bromide in a room temperatur...
متن کاملGraft Copolymers of Poly(methyl methacrylate) on Cellulose and Their Use as Supports in Metal Ion Sorptiona
We have reported earlier some work on the grafting of vinyl monomers onto cellulose extracted from pine needles. The grafting was carried out both by radiation1,2 and by a chemical initiation method3,4. The optimum grafting conditions for a single monomer were used to co-graft it with other comonomers so as to improve upon the intrinsic properties of the cellulose backbone5,6. These graft copol...
متن کاملStudy of Immobilization of Protease and Sorption of Bsa on Cellulose, Cellulose Derivatives, and Graft Copolymers
In order to develop novel polymeric supports based on cellulosics, cellulose extracted from pine needles, a perennial resource material available in huge quantities as waste, was graft copolymerized with vinyl monomers. Cellulose, cellulose derivatives, and their graft copolymers with highest percent grafting (Pg) were used as supports for immobilization of an industrially important protease en...
متن کاملThe preparation of graft copolymers of cellulose and cellulose derivatives using ATRP under homogeneous reaction conditions.
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 ...
