Research on the Graft Copolymerization of EH-lignin with acrylamide
Lignin isolated from enzymatic hydrolyzed cornstalks (EH-lignin) is a renewable natural polymer noted for its versatility and applicability in a variety of uses. Graft copolymerization of EH-lignin with acrylamide (AM) and the application of this copolymer as a flocculant in dye wastewater treatment were studied in this article. The influences of some factors on yield of copolymer and the graft...
متن کاملpreparation of acrylamide-based anionic polyelectrolytes for soil establishment
synthetic water soluble acrylamide-based polymers have wide range of ap-plications in the feld of soil establishment and non-desertifcation. in this research, the acrylamide-based anionic polyelectrolytes were prepared by solution polymerization. the polymerization was carried out using aibn as a radical initiator and at different degrees of anionic charges ranging between 10% and 30...
متن کاملOptimized Conditions for Graft Copolymerization of Poly(acrylamide) onto Rubberwood Fibre
Graft copolymerization of acrylamide (Am) onto rubberwood fibre (RWF) was carried out by free radical initiation. Ceric ammonium nitrate was used as an initiator system. The effects of temperature, dose of initiator, ratio of monomer to fibre, and nitric acid concentration, on the grafting percentage were investigated. The optimum reaction temperature was found to be about 50°C for 4h and with ...
متن کاملInverse microemulsion copolymerization of butyl acrylate and acrylamide: kinetics, colloidal parameters and some model applications
The inverse microemulsion copolymerization of acrylamide and butyl acrylate initiated by ammonium peroxodisulphate, a water-soluble initiator, and stabilized by anionic emulsifiers sodium bis-2ethylhexylsulfosuccinate and sodium dodecylsulphate (SDS) has been studied. An increase of SDS concentration was observed to increase both the rate of polymerization and the particle size. The average num...
متن کاملReactivity ratios, and mechanistic insight for anionic ring-opening copolymerization of epoxides.
Reactivity ratios were evaluated for anionic ring-opening copolymerizations of ethylene oxide (EO) with either allyl glycidyl ether (AGE) or ethylene glycol vinyl glycidyl ether (EGVGE) using a benzyl alkoxide initiator. The chemical shift for the benzylic protons of the initiator, as measured by (1)H NMR spectroscopy, were observed to be sensitive to the sequence of the first two monomers adde...
