Grafting of Acrylonitrile, and Methyl on Carboxy Methyl Cellulose Cell ulose, Methacry late F. E. OKIEIMEN* and D. E. OCBEIFUN University of Benin, Department of Chemistry, Benin City, Nigeria SYNOPSIS Graft copolymers of acrylonitrile (ACN), methyl methacrylate (MMA), and their mixtures on carboxy methyl cellulose (d.S 0.4-0.5) were prepared

Modification of natural polymers: Part IV Graft

Grafting of MA onto cellulose has been studied earlier. Ide6 grafted various vinyl monomers including MA onto cellulose using ceric ammonium nitrate (CAN) as initiator. Sharma and Daruwalla7 reported grafting of MA individually and in binary mixtures onto cotton yarn by emulsion technique initiated by ceric ions.

PEER-REVIEWED ARTICLE Lignocellulose

methacrylate and acrylonitrile onto cellulose in the presence of ceric ions with acrylonitrile as the principal monomer. In the present manuscript, efforts have been made to modify the surface of Agave americana fibers through graft copolymerization of binary monomer mixture of methyl methacrylate and acrylonitrile using Ce (IV) ion HNO3

CHARACTERIZATION AND MONOMER REACTIVITY RATIOS OF GRAFTED

grafting, the graft copolymerization was also studied using different feed compositions, ranging from 0.15 to 0.85. The reactivity ratios of 4NPA and MMA by ATRP on cellulose were determined using

SYNTHESIS AND CHARACTERIZATION OF GRAFT COPOLYMERS OF 2

by using ceric ammonium nitrate as initiator, and this grafted cellulose was investigated for sorption of Cu, Cr, Ni and Pb ions (Nada et al. 2007). 2-Hydroxyethyl methacrylate (HEMA) is a monomer of gelling nature (Chu et al. 1995; Karlsson and Gatenholm 1996)
