“…However, we observed that the concentration of hydroperoxy groups remained unchanged when leaving the irradiated polymer for 24 h. Gawish et al reported that the graft yields on preirradiated polypropylene remained unaffected even after 5 days of storage of the irradiated samples. 18 Esters are known to react with potassium hydroxamate under mild conditions and form acylhydroxamic acids, (N-hydroxyacylamides) 11 :…”

ABSTRACT:Crosslinked poly(N-vinylpyrrolidone), preirradiated in air with ␥ rays, was grafted with ethyl acrylate in dioxane and water. A detailed study of grafting was made under various reaction conditions. The graft copolymer was treated with potassium hydroxamate in ethanol. The resulting polymer contained pendant hydroxamic acid groups (OCOONHOH) and was studied for the formation of complexes with Fe(III), Cu(II), and Ni(II). The effect of pH on the metal ion uptake by the polymer was also studied.

“…Thus, a high local concentration of the monomer around the formed active sites resulted in a high grafting yield. 15,16 Effect of the inhibitor The addition of some inorganic salts to the reaction mixture was investigated in an attempt to minimize the homopolymerization and to optimize the grafting conditions. The concentration of these salts was kept constant at 0.5 wt %, and the results are given in Table II.…”

ABSTRACT:The introduction of new characteristics to some synthetic polymers was achieved through the ␥-radiation-induced graft copolymerization of an acrylamide/vinyl acetate comonomer onto polypropylene films for the preparation of synthetic membranes. The influence of the reaction conditions on the grafting yield, such as the solvent and its composition and the inhibitor and its concentration, was investigated. An alkaline treatment was carried out for the prepared graft copolymer to improve its ion-exchange property. The grafted and treated membranes were characterized to determine the structural changes with X-ray diffraction and Fourier transform infrared spectroscopy. The mechanical properties, swelling behavior, and electrical conductivity for the graft copolymer were studied. Improvements in the tensile strength, electrical conductivity, and hydrophilicity with grafting were observed. The KOHtreated membranes possessed greater hydrophilic properties than the untreated ones. The possibility of practical uses for these membranes in the removal of cesium-134 and cobalt-60 from their liquid wastes was also investigated. © 2004 Wiley Periodicals, Inc.

“…Polypropylene (PP), one of the most available versatile polymers, faces many problems in blending and compounding owing to its hydrophobicity, especially lacking any reactive functional groups [1,2]. The grafting technique with reactive monomers onto PP has been widely used in the modification of PP to overcome these problems [3][4][5][6].…”

Mechanochemistry: a novel approach to graft polypropylene with dual monomers (PP-g-(MAH-co-St))

Mechanochemistry as an energy-saving and highly efficient synthetic method emerges great potential in various chemical syntheses. The multi-phase compatibilizer polypropylene (PP) grafted with maleic anhydride (MAH) and styrene (St) (PP-g-(MAH-co-St)) was successfully obtained by mechanochemical method without any solvent within minutes. The PP-g-(MAH-co-St) with G MAH = 0.24-1.40 % were made by mechanochemistry successfully. The impact of monomers concentration, initiator concentrations, particle size of PP, ball-milling time and ball-milling speed on the grafting proportion of MAH onto PP (G MAH ) was also investigated. The optimum conditions for PP-g-(MAH-co-St) (G MAH = 1.40 %) by ball milling were particle size of PP, 0.150-0.250 (mm); MAH/PP ratio, 6 % (m/m); St/PP ratio, 6 % (m/m); DCP/PP ratio, 0.3 % (m/m) at 400 r/min in 30 min. Infrared (IR) spectra and 1 H NMR spectra confirmed the incorporation of MAH and St onto the PP backbone, which also indicated ball milling was an efficient and effective way for the graft of PP-g-(MAH-co-St).Electronic supplementary material The online version of this article (
