More specifically, the present invention discloses a reaction product of: a fatty acid composition in the range of 60-95% wt/wt; a glycerol tricarboxylate in the range of 0.1-10.0% wt/wt; a polysulfone in the range of 0.1-5.0% wt/wt; a polyamine in the range of 0.1-5.0% wt/wt; an alkylated benzene sulfonic acid in the range of 0.1-5.0% wt/wt; and a phenol derivative in the range of 0.1-10.0% wt/wt. The present invention also discloses a single-pot process for the preparation of said reaction product.
Methods and compositions for clarifying produced waters for boiler feed waters
Disclosed are methods and compositions for coagulating and clarifying produced waters for use as boiler feed waters, for example for the generation of steam. The methods and compositions are especially useful for treatment of produced waters from steam-injection methods of tertiary oil recovery such as steam-assisted gravitational drainage. Disclosed are compositions comprising a first copolymer having a high molecular weight and bearing a low molar cationic charge and a second copolymer having a lower molecular weight and bearing a high molar cationic charge. The compositions are suitable for addition as coagulants to produced waters that have been treated by warm lime softening. Also disclosed are methods of treating produced waters from steam-injection oil recovery for use as boiler feed waters to generate steam in such steam injection methods.
ELECTRODE INTERFACE LAYER MATERIAL, ZWITTERIONIC POLYMER AND ORGANIC PHOTOVOLTAIC DEVICE
An electrode interface layer material is generated by using a modifier to react with polyethyleneimine, and the amine group on the polyethyleneimine is converted into an ammonium group by reacting with the modifier to form a zwitterionic polyethyleneimine. When an active layer containing a non-fullerene material is formed on the surface of the electrode interface layer, or when the surface of the electrode interface layer is contacted with a non-fullerene material, the possibility that the non-fullerene material is destroyed by the amine groups in the electrode interface layer can be reduced. In addition, the aforementioned electrode interface layer material or zwitterionic polymer is used for an organic photovoltaic device.
CATIONIC POLYMERS WITH D-FRUCTOSE SUBSTITUENTS
The invention relates to new cationic polymers conjugated with D-fructose, as a result of which they can selectively interact with specific structure elements on cell surfaces. The problem was that of creating novel, biocompatible, easy-to-produce, D-fructose-conjugated cationic polymers that have a higher selectivity with respect to certain cell types. To solve this problem, the invention proposes cationic polymers with covalently bonded D-fructose of general formula (I) with the following components: a) cationic polymer: macromolecular compounds of n repeat units with one or more positive charges; b) linker: a unit that links the cationic polymer with D-fructose or derivatives of D-fructose by means of any alkyl or aryl group, any alkenyl or alkinyl group, an ether, thioether or amine, an ester, amide or other carboxylic acid derivative, a heterocycle (e.g. triazole or m maleimide), a disulphide, an imine or an imide; c) D-fructose: one or more D-fructoses or D-fructose derivatives in an open-chain, furanoid or pyranoid structure, not glycosidically linked via one of the five possible carbon atoms (1, 3, 4, 5, 6).
DISPERSIBLE ANTIMICROBIAL COMPLEX AND COATINGS THEREFROM
Disclosed are latexes, suspensions, and colloids having a cationic antimicrobial compound complexed with an anionic surfactant. The surfactant may have greater affinity for the antimicrobial compound than other anionic surfactants and other anions in the latex, suspension, or colloid that contribute to disperse phase stability to prevent disrupting the dispersions. Dispersions containing the antimicrobial compound may therefore have a shelf life comparable to dispersions that are otherwise identical but lack the cationic antimicrobial compound and its complexed anionic surfactant. Coatings made with the complexes can exhibit essentially undiminished antimicrobial activity.
Anion exchange stationary phases based on crosslinked hydroxyalkylamine layer and glycidol
An anion exchange stationary phase includes a negatively charged substrate particle, a base condensation polymer layer, a crosslinked ethanolamine condensation polymer, and a glycidol condensation layer. The crosslinked ethanolamine condensation polymer layer can be covalently attached to the base condensation polymer layer. The crosslinked ethanolamine condensation polymer layer can be formed by a condensation reaction product of a polyepoxide compound and ethanolamine. The glycidol condensation layer can be formed by the treatment of glycidol. The anion exchange stationary phase are suitable for separating a variety of haloacetic acids and common inorganic anions in a single chromatographic run in less than 20 to 35 minutes.
