Polymer science is, of course, driven by the desire to produce new materials for new applications. The success of materials suchas polyethylene, polypropylene, poly(vinyl chloride) and polystyrene is such that these materials are manufactured on a huge scaleand are indeed ubiquitous....

Polystyrene is one of the important commercial polymers, widely used in various industrial fields. One of the important uses of PS is in the manufacture of cover signals lamp of some automobiles. PS is subjected to the irradiation of sunlight on outdoor exposure....

The low cost and excellent performance of poly(vinyl chloride) (PVC) make it a very attractive and suitable plastic for a wide variety of applications. With respect to the production and consumption of synthetic materials, it stands third in the world after polyethylene and polypropylene. However, PVC suffers from poor thermal and light stability....

Poly(vinyl chloride), better known by its abbreviation PVC, is one of the most versatile plastics. It is the second largest manufactured resin by volume worldwide; currently, its production per annum exceeds 31 million tons....

New stationary phase for high performance liquid chromatography had been prepared by the reaction of congo red solution with amberlite anion exchange. The F.T.I.R elemental analyses have configured the attachment of congo red on the resin as has indicated by the physical appearance of the new resin....

Five transition metal complexes of Ni(II), Cu(II), Zn(II), Cd(II) and Sn(II) with {4-amino-5-(pyridyl)-4H-1,2,4-triazole-3-thiol}, as a ligand (L) has been prepared in alcoholic medium.The photostabilization activity of these compounds was determined by monitoring the carbonyl and hydroxylindexes, weight loss method with irradiation time....

Synthesis of PVC polymer bonded to heterocyclic units is the field of our research ....

This work was made to study the photochemistry of riboflavin and the kinetics of riboflavin degradation after exposure to UV-Vis light phosphate buffer solution at different pH interval (2-10) with the same concentration (5?...

Three new ligands have been prepared in this work, which were chosen to synthesis a new set of transition metal complexes [Cu (II), Ni (II), Hg (II), Cd (II) and Co (II)]....

The coordination chemistry of hydrazones is an intensive area of study and numerous transition metal complexes of these ligands have been investigated, which stemmed from the interest in the biological and pharmacological properties of these hydrazones....

The work described in this thesis, 2-thioacetic acid benzothiazole chelate complexes. Infrared, ultraviolet–visible, spectrophotometric techniques, magnetic susceptibility, atomic absorption? conductivity measurement and other physical properties were used to characterize the free ligand and the above chelate complexes....
