Journal ArticleDOI
Compatibility in blends of two random copolymers having a common monomer segment
TL;DR: Etude theorique et experimentale sur les melanges copolymere chlorure vinylique-acetate vinylique/PVC chlore (considere comme copolymeme chlorure/vinylique-dichloro-1,2 ethylene) as discussed by the authors.
Journal ArticleDOI

TL;DR: In this paper, double spherulites like concentric circles were observed for poly(ϵ-caprolactone)-block-poly(ethylene glycol)-blockpoly(π)-poly( ϵ)-caprolACTone) (PCL-b-PEG-b -PCL) triblock copolymers, with PCL compositions of 66 and 60 wt% respectively.
Journal ArticleDOI

TL;DR: In this article, the structure formation of poly(ethylene oxide)-poly(ɛ-caprolactone) block copolymers (PEG-PCL) in which the melting temperatures of the components are close to each other were elucidated using differential scanning calorimetry (DSC), small-angle X-ray scattering (SAXS), and wide-angle x-ray diffraction (WAXD) techniques.
Journal ArticleDOI
Immobilization of Enzyme into Poly(vinyl alcohol) Membrane
TL;DR: The pH activity curve for the immobilized enzyme was superior to that for the native one, and thermal stability was improved by immobilization with bovine albumin, and the apparent Km appeared to be affected by the molecular size of the substrate.
Journal ArticleDOI
Thermodynamics of polymer blends of poly(vinyl methyl ether) and polystyrene
TL;DR: Les variations d'enthalpie and les volumes en exces mesures au voisinage de la LCST sont negatifs as mentioned in this paper, which suggere l'existence d'une interaction specifique dominance and qu'une LCST existe au moins theoriquement.
