The Preparation and Properties of Acrylic and Methacrylic Acid Grafted Cellulose Prepared by Ceric Ion Initiation. Part I. Preparation of the Grafted Cellulose

Degradation of Acrylic Acid-Grafted Cellulose in Aqueous Medium With Radical Initiators

“…Mc Dowall, Gupta and Stannett [34] have reported yield up to 60% and less than 5% homopolymer. Vitta, Stahel and Stannett [35] prepared a solution dissolving a known amount of CAN in 0.1 N nitric acid and mixing with deionised water. Copper powder was added to inhibit homopolymer formation.…”

Plasma modification of natural cellulosic fibres

“…The main drawback of this method is the generation of highly toxic wastes. 23 In recent years, low-temperature plasma technology for surface modifi cation of textile substrates has attracted increasing attention. It has been established that plasma treatment plays a key role in the enhancement of textile fi bres and fabrics properties, such as improved wettability, dyeing, water repellency, lowered moisture content, and decreased surface resistivity.…”

“…It has been established that plasma treatment plays a key role in the enhancement of textile fi bres and fabrics properties, such as improved wettability, dyeing, water repellency, lowered moisture content, and decreased surface resistivity. 24 Several studies on plasma surface modifi cation of cellulose-based textiles have been conducted, using glowdischarge technology at low pressure [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] as well as barrier discharge and corona treatments at atmospheric pressure. [41][42][43][44][45][46][47][48][49][50] In both cases, active particles such as radicals, ions, electrons and photons are generated, which under reduced pressure have a much larger free path length as compared with the process at atmospheric pressure.…”

Enhancing both the mechanical and chemical properties of paper sheet by graft co-polymerization with acrylonitrile/methyl methacrylate

“…Graft copolymerization reactions of acrylic acid, acrylates and acrylonitrile on cellulosic materials have been investigated (Vita et al, 1985(Vita et al, , 1986Okieimen and Ebhoaye, 1986a, 1986b, 1986cOkieimen, 1987 andYousef, 1990;Saikia and Ali, 1999;Qiu and Hu, 2013) by the use of ceric ammonium nitrate in aqueous medium at different temperatures. The variation in the level of incorporation of poly(acrylic acid) grafts on the cellulosic substrate and the dependence of the water and saline retentions of the graft copolymers on the graft level were examined.…”
