Current fundamental researches in the field of potentiometry demonstrate perspectives using polymeric nanostructured materials as ion-to-electron transducers Solid-Contact Potentiometric Sensors (SCSs). This paper reports preparation and comparative study plasticized Poly(Vinyl Chloride) (PVC) membranes modified with fullerene C60, single-walled carbon nanotubes SWCNTs, multiwalled nanotubes, g...
flory fox, kurata-stockmayer, berry, inagaki-suzuki-kurata, stockmayer-fixman and ahmad-baloch methods based on the excluded volume theory have been applied to poly(vinyl chloride)-cyclohexanone system to obtain kq and the radius of gyration. a discussion on the reliability of these methods is given. the stockmayer-fixman and ahmad-baloch methods are found to be equally applicable.

We synthesized and designed four new modified poly(vinyl chloride) structures to develop various polymer derivatives enhance their photo-stability. Commercially available was synthetically into a containing aromatic Schiff base moieties. First, the PVC reacted with ethylene diamine from one side by using an equivalent of extra increase probability preventing cross-linking versus two-sided react...
AIMS To investigate the presence of liver lesions and their relation with vinyl chloride monomer (VCM) exposure or other personal risk factors, in workers involved in the production of VCM and polyvinyl chloride (PVC). METHODS A liver ultrasonography examination was conducted in 757 workers, some of whom had long standing service in the production of VCM and PVC. The study involved: assessmen...
175.210 Acrylate ester copolymer coating. 175.230 Hot-melt strippable food coatings. 175.250 Paraffin (synthetic). 175.260 Partial phosphoric acid esters of polyester resins. 175.270 Poly(vinyl fluoride) resins. 175.300 Resinous and polymeric coatings. 175.320 Resinous and polymeric coatings for polyolefin films. 175.350 Vinyl acetate/crotonic acid copolymer. 175.360 Vinylidene chloride copolym...
In this work polyaniline nanocomposites were synthesized in aqueous media by using ammonium proxy disulfat (APS) (10g/l) as an oxidant in the presence of hydroxy propyl cellulose (HPC) (2,5,10 g/l) as a surfactant, poly (vinyl chloride) (10,30 g/l) as an additive and sulfuric acid (H2SO4). The effects of concentration of surfactant and additive on morphology have been ...
