Study of Surface Tension of Binary Mixtures of Poly (Ethylene Glycol) in Water and Poly (Propylene Glycol) in Ethanol and its Modeling Using Neural Network

Modification of Poly(Ethylene Terephthalate) Fiber by Grafting of Acrylic Acid/Acrylamid for Removel of Pb+2 from Aqueous Solutions

: A new fibrous adsorbent was prepared by grafting Acrylic Acid /Acryl Amide (AA/AAm) co-monomers onto Poly(Ethylene Terephtalat) (PET) fibers. The resulting sorbent has been characterized by Fourier Transform InfraRed spectroscopy (FT-IR), Thermo Gravimetric Analysis (TGA), Scanning Electron Microscopy (SEM) and elemental analysis and studied for the preconcentration and ...

Pervaporation of alcohol-toluene mixtures through polymer blend membranes of poly ( acrylic acid) and poly (vinyl alcohol)

Homogeneous membranes were prepared by blending poly (acrylic acid) with poly (vinyl alcohol). These blend membranes were evaluated for the selective separation of alcohols from toluene by pervaporation. The flux and selectivity of the membranes were determined both as a function of the blend composition and of the feed mixture composition. The results showed that a polymer blending method coul...

Co-Nonsolvency of Poly(n‐isopropylacrylamide) in Deuterated Water/Ethanol Mixtures

Small-angle neutron scattering was used to investigate poly(N-isopropylacrylamide) (PNIPAM) polymer solutions in d-water/d-ethanol mixtures. A wide poor-solvent region was observed for mixtures near 60% d-water/40% dethanol mixture. Spinodal lines were determined, permitting a mapping of the mixing/demixing regions of the phase diagram which comprises two main branches: the left branch (with mo...
