Grafting Copolymerization of Cationic Vinyl Monomer with Quaternary Ammonium Groups onto Polypropylene
Grafting polymerization was a valuable method for the modification of the chemical and physical properties of polymer surfaces. In this paper, the grafting of cationic vinyl monomer with quaternary ammonium groups, methacryloxyethyltrimethyl ammonium chloride (DMC), onto the isotactic polypropylene (iPP) granule was performed by suspension solid-state grafting process. The techniqu...
متن کاملRadiation-Induced Graft Copolymerization of Acrylonitrile onto Kappa-Carrageenan
The monomer, acrylonitrile, was graft copolymerized onto kappa-carrageenan (kC) using γ-rays as initiator. The reactions were carried out in a homogenous aqueous medium. After removal of the homopolymer, the graft copolymer was characterized by FTIR spectroscopy. A plausible mechanism of grafting has also been suggested. The effect of various factors affecting on grafting, i.e. dose of δ-rays a...
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...

Thermal stability of cation exchange, PFA-g-polystyrene sulfonic acid membranes prepared by radiation-induced graft copolymerization of styrene onto PFA films followed by sulfonation was studied by thermal gravimetric analysis (TGA) and oven heat treatment. The tested samples included original and grafted PFA films as reference materials. All the membranes showed multistep decomposition pattern...
