Statistical polymer method: Modeling of macromolecules and aggregates with branching and crosslinking, formed in random processes

The statistical polymer method is based on the consideration of averaged structures of all possible macromolecules of the same weight. One has derived equations allowing evaluation of all additive parameters of macromolecules and their systems. The statistical polymer method allows modeling of branched crosslinked macromolecules and their systems in equilibrium or non-equilibrium. The fractal consideration of statistical polymer allows modeling of all kinds of random fractal and other objects studied by fractal theory. The statistical polymer method is applicable not only to polymers but also to composites, gels,associates in polar liquids and other aggregates

The Quantitative Theory of Diffraction by Spiral Nanotubes

The quantitative theory of diffraction by spiral nanotubes of any chemical composition is offered. Distribution of diffraction intensities along layer lines and layer planes, strong and diffuse reflexes, pseudoorthogonality effect has been simulated and analyzed. The investigation is oriented to electron microdiffraction from a single nanotube

Aminolysis Reaction of Glycerol Carbonate in Organic and Hydroorganic Medium

Aminolysis reaction of glycerol carbonate with primary amine in organic and hydroorganic media leads to the formation of two hydroxyurethane isomers and a partial decomposition of glycerol carbonate into glycerol. Aminolysis with a secondary amine promotes the condensation reaction and limits the formation of glycerol. The ratio of α versus β was determined by zgig 13C NMR. This technique permits computing the yield of α and β products in the medium. The quantity of glycerol was determined by GC analysis. The ratio of the isomers and the amount of glycerol depend on the amine and the solvent. Kinetic investigations reveal that, in hydroorganic medium, the more the alkyl chain of the amine increased, the less glycerol was formed. On the contrary, in organic medium, the alkyl chain of the amine does not play a major role in the formation of glycerol

Renewable Self-Blowing Non-Isocyanate Polyurethane Foams from Lysine and Sorbitol

Copolymerisation of a sorbitol-derived bis-carbonate with simple diamines, including cadaverine that was sustainably produced from lysine, under solvent-free conditions was shown to produce rigid foams. Thermogravimetric analysis carried out in tandem with infrared spectroscopy of the released gases confirmed that the foaming agent was carbon dioxide produced during the polymerisation process itself. Such a bio-based foam, being made under mild conditions from stable, benign precursors, with no toxic isocyanates, has great potential application for both thermal insulation and packaging
