Homogeneous graft copolymerization of methyl methacrylate (MMA) onto cellulose was carried out in N, N – dimethyl acetamide/LiCl (DMAc/LiCl) and dimethyl sulfoxide/ paraformaldehyde (DMSO/PF) solvent system taking ceric ammonium nitrate (CAN), benzoyl peroxide (BPO) and tin (II)-2ethyl hexanoate [Sn(Oct)2] as initiators. Different grafting parameters like graft yield (GY), grafting efficiency (...
متن کاملModeling of the Copolymerization Kinetics of n-Butyl Acrylate and d-Limonene Using PREDICI "672
Kinetic modeling of the bulk copolymerization of D-limonene (Lim) and n-butyl acrylate (BA) at 80 ̋C was performed using PREDICIr. Model predictions of conversion, copolymer composition and average molecular weights are compared to experimental data at five different feed compositions (BA mol fraction = 0.5 to 0.9). The model illustrates the significant effects of degradative chain transfer due...
متن کاملGraft Copolymerization onto Chitosan V: Grafting Ethyl Acrylate onto Chitosan Initiated By Ceric Ion and Its Anti Microbial Activity
Ethyl Acrylate was grafted onto chitosan by using the ceric ammonium nitrate as the initiator. The effect of initiator concentration, monomer concentration, time & temperature on % G and % E were studied. The grafted samples were characterized using FTIR, SEM, atomic force microscopy AFM and XRD methods. Xray diffraction showed changes in the crystallinity pattern of chitosan after the copolyme...
متن کاملGraft copolymerization of methyl acrylate on chitosan: Initiated by ceric ammonium nitrate as the initiator-characterization and antimicrobial activity
Methyl acrylate was grafted onto chitosan by using the ceric ammonium nitrate as the initiator. The effect of initiator concentration, monomer concentration, time & temperature on % G and % E were studied. The grafted samples were characterized using FTIR, SEM, TGA methods. Evidence of grafting was confirmed by FTIR spectroscopy. The morphology evaluated by SEM. The thermal analysis indicated t...
