Structure moléculaireIndex. décimale : 667.9 Revêtements et enduits Résumé : Several C13 NMR techniques are introduced to address the problem of structure determination of photopolymerized polyolacrylates, and to study both the liquid and solid states of acrylic monomers and oligomers, as well as the network structure formed upon their photopolymerization. By measuring the relative integration of specific peaks in the carbon spectra as a function of the time of irradiation and laser power, the relative reactivity of monomers/ oligomers used in the early stages of polymerization is determined. Changes in crosslink density and in the mobility of the polymeric chains can be followed throughout the photopolymerization process by monitoring proton T1ρ relaxation times. The degree of crosslinking is correlated to the relaxation times and it increases with an increasing power of the irradiating laser even under conditions where the degree of conversion, as measured by quantitative infrared absorption of the 810 cm-1 band of the acrylate is almost unchanged.

Revêtements poudre:Peinture poudreIndex. décimale : 667.9 Revêtements et enduits Résumé : Solvent based non-yellowing 2K polyurethanes nowadays offer the best combination of properties for the production of high quality coatings. Due to their flexibility, gloss retention and weather resistance, polyurethane coatings are used all over the world in a variety of applications. A number of different hydroxylated resins are available to produce coatings with property profiles ideally suited for specific requirements. Environmental considerations and national legislations impose a continuous reduction of solvent emissions. So both resin producers and paint manufacturers are confronted with those new regulations and the necessity to adjust their production to new stipulations. In this study, it will be demonstrated how the solvent content of a PU formulation can be influenced by the correct choice of a polyisocyanate hardener.

Gluconique, AcideL'acide gluconique (C6H12O7) est un acide très répandu aussi bien chez les animaux que dans les plantes. Il est le plus souvent intégré dans une molécule plus grande comme c'est le cas dans diverses gommes. Il est obtenu à partir de la gomme d'acacia, à partir de laquelle on l'isole sous la forme de cristaux en aiguilles fondant à 165 °C. Il est soluble dans l'eau et l'alcool. Il est autorisé en Europe comme additif alimentaire (E5748).

Sulfate de ferIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The stabilization of type I collagen is important to applications of collagen protein. In this paper, the stabilization of type I collagen with Fe-gluconic acid has been studied by various methods such as UV-vis and IR spectra, CD and DSC etc. Gluconic acid can form a compound with ferrous sulphate which can improve the thermal stability of type I collagen to an extent greater than that of Fe atone. The reaction molar ratio was 1:3 between Fe and gluconic acid. The increase of thermal stability is owed to cross-link formation between the compound and collagen.

Succinique, AcideL'acide succinique est un diacide carboxylique aliphatique, dénommé également acide butane-1,4-dioïque et de formule semi-développée HOOC–CH2–CH2–COOH.
Il est présent dans tous les organismes vivants et intervient dans le métabolisme cellulaire, en particulier dans le métabolisme des lipides entre l'acide cétoglutarique et l'acide fumarique lors du cycle de Krebs dans la mitochondrie.Index. décimale : 667.9 Revêtements et enduits Résumé : A UV curable bio-oligomer on succinic acid and having three different reactive carbon-carbon double bonds on the backbone was evaluated.
