Graft copolymerization of acryl-amide onto guar-gum has been carried out in the presence of potassium per sulphate as a redox initiator. The prepared graft copolymer was characterized by various techniques such as FT-IR, SEMEDX and TGA-DTA-DTG. Activated charcoal was also studied as the adsorbent in the present study to evaluate their adsorption capacity for Cr (Vl) and compared it with indigen...

The title compound, glycidamide (systematic name: oxirane-2-carboxamide), C3H5NO2, is the mutagenic and genotoxic metabolite of acryl-amide, a food contaminant and industrial chemical that has been classified as being probably carcinogenic to humans. Synthesized via the reaction of acrylo-nitrile and hydrogen peroxide, it crystallizes with both enanti-omers occurring as two crystallographically...

The aim of this present study was to develop a pH sensitive interpenetrating polymeric network (IPN) hydro gels (HG) based on chitosan-acryl amide-grafted-poly ethylene glycol (CTS-AM-PEG) followed by hydrolysis that are cross-linked with glutaraldehyde (GA). Cefotaxime is an antibiotic drug was successfully loaded in these IPNHG’s. The HGs formed were characterized by Fourier transform infrare...

In this work, a series of hydrogel nanocomposites were prepared by grafting acrylic acid and acrylamide on gelatin in the presence of Na-montmorillonite (Na-MMT) nanoparticles. The characterizations of hydrogel nanocomposites were examined by swelling experiments, Fourier transform infrared (FT-IR) spectroscopy, X-Ray diffraction (XRD) patterns and thermogravimetric analysis (TGA). Scanning ele...

The title compound, C19H19NO3S, was produced by the self-reaction of N-cinnamyl-N-tosyl-acryl-amide in the presence of palladium(II) acetate via an intra-molecular C-C coupling reaction and C-H activation. There are two chiral C atoms in the mol-ecule, but the crystal is a racemic system due to a lack of chiral separation. The five-membered ring is twisted about the methyl-ene-methane bond, and...

Reaction of 2-(4-chloro-3,3,7-trimethyl-2,3-dihydro-1H-indol-2-yl-idene)propane-dial with hydroxyl-amine gives the title compound, C(14)H(14)ClN(3)O, in which the ring N atom is essentially planar [sum of angles around the ring N atom = 361°], indicating conjugation with the 2-cyano-acryl-amide unit. The orientation of the acetamide group arises from intra-molecular hydrogen bonding between the...

PURPOSE This study aimed to discover a way to increase the bond strength between bis-acryl resins, using a comparison of the shear bond strengths attained from bis-acryl resins treated with light curing, pressure, oxygen inhibition, and heat. MATERIALS AND METHODS Self-cured bis-acryl resin was used as both a base material and as a repair material. Seventy specimens were distributed into seve...
