ABSTRACT. Acrylated Parkia biglobosa medium oil alkyd prepared by the reaction between an acid containing acrylic copolymer and a monoglyceride followed by the addition of polyol and dibasic acid has been investigated for improved properties. The results revealed that acid functional acrylic copolymers containing maleic anhydride as a functional co-monomer can successfully be used to modify alk...

The preparation of vanadyl pyrophosphate (VPO) strongly influences their catalytic activity in partial oxidation of butane to maleic anhydride. The characteristics of VOHPO4•0.5H2O, (called “the precursor” in this paper) are strongly influenced by the reagents, the ratio of phosphorous to vanadium, the nature of the solvent and the conditions of the reduction step during the preparation. Synhes...

The early response of infant mice to foot-and-mouth disease viral antigens, measured by greater resistance and increased serum-neutralizing antibody, was enhanced by divinyl ether-maleic anhydride (DVE/MA). Preparations of known antigen concentration were used to study various parameters influencing this enhancement. Resistance and antibody levels were increased when DVE/MA was administered wit...

A vanadium oxide-carbon nanotube composite was prepared by solution-based hydrolysis of NH4VO3 in the presence of carbon nanotubes. The carbon nanotubes induce the nucleation of the 1D vanadium oxide nanostructures, with the nuclei growing into long freestanding nanorods. The vanadium oxide nanorods with the lengths up to 20 μm and the widths of 5–15 nm exhibit a well-ordered crystalline struct...

In this research, at different quantities as fillers, Boric Acid, Calcite (CaCO3), SPT (Sodium Perborate Tetrahydrate) and coupling matters, 3%, MAPE (Maleic Anhydride Grafted Polyethylene), Titanate Silanyl (Vinyltriethoxysilane) were added waste paper. Composite boards pressed cut in 1 × 30 cm. order to identify some properties of the produced boards, experimental works applied according stan...

In this study, new compounds of Schiff bases were prepared (1-6), from the reaction sulfamethoxazole with benzaldehyde derivatives. (1-6) converted to 1,3-Oxazepine-4,7-dione and 1,3-Benzooxazepine-4,7-dione derivatives (7-18) through maleic anhydride as well phthalic using crushing, grinding microwave irradiation method. The structures all have been identified by (I.R) technique, also some (1H...

A Highly efficient protocol has been developed for the synthesis of 2-hydrazolyl-4-thiazolidinone derivatives installing a one pot three component coupling reaction of an aromatic aldehyde, thiosemicarbazide and maleic anhydride using guanidine hydrochloride as highly inexpensive and environmentally friendly catalyst under solvent free condition at 1200C with good to excellent yields, It offers...

Polypropylene (PP) has poor adhesion to metals and other surfaces for its chemical structure. Hence, chemical modification of PP is necessary for metal surface coating application. In this research, grafting of maleic anhydride (MA) onto co(propylene-b-ethylene) in the presence of a dicumyl peroxide (DCP) was accomplished in a single screw extruder. Characteristics of the modified polymer were ...
