  • Patent number: 11806355
    Abstract: The invention relates to compositions containing water-soluble poly(oxazoline) and organic polymer particles chosen from the group of polyolefins, polyvinyl aromatics, polyvinyl esters, polyesters, polyamides, polyimides, polycarboxylic acids, polycarboxilic acid esters, polycarboxylic acid amides, polynitriles, polysulfonic acids, polyketones, polysulfones, polymeric polyols, polyurethanes, proteins, polymeric carbohydrates, nucleic acids or from a mixture of two or more of these polymers.

  • Patent number: 11637318
    Abstract: A process can be used to produce a charge storage unit, especially a secondary battery, the electrodes of which contain an organic redox-active polymer, and which includes a polymeric solid electrolyte. The solid electrolyte is obtained by polymerizing from mixtures of acrylates with methacrylates in the presence of at least one ionic liquid, which imparts advantageous properties to the charge storage unit.

  • Publication number: 20220401577
    Abstract: The invention relates to a nanostructured active ingredient carrier system, in particular for reducing cytotoxic properties owing to the use of sheath polymer and the transport resulting therefrom, for interactions with cell membranes during the transport of hydrophilic constituents and, in connection therewith, the generation of an early endosomal release of the interaction complex from the carrier system. The problem addressed by the present invention is that of specifying a nanostructured active ingredient carrier system which avoids the disadvantages of the prior art and in particular permits a reduction in cytotoxic properties owing to the use of a sheath polymer and the transport resulting therefrom.

  • Patent number: 11530296
    Abstract: 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.

  • Publication number: 20200348271
    Abstract: Disclosed is a method for the determination of impurities in polyalkylene ethers and polyalkylene amines comprising the steps i) introducing polyalkylene ethers or polyalkylene amines as an analyte into a chromatography column containing monolithic silica gel as a stationary phase, ii) eluting the analyte with a liquid elution agent having such a polarity that the analyte is in adsorptive equilibrium with the stationary phase during chromatography, iii) detecting the components of the analyte at the exit-side end of the chromatography column, receiving a chromatogram, which shows different components of the analyte and its qualitative amount depending on the elution time of the individual components, and iv) identifying bands in the chromatogram having a low height or area compared to the band with the largest height or area as an indication of the presence of impurities in the analyte. The method allows in an easy manner to identify impurities in the sample.

  • Publication number: 20200339945
    Abstract: Cell cultures comprising poly(oxazoline) stabilizers and use of poly-(oxazolines for stabilizing cell cultures Described are cell cultures containing in a cell culture medium one or more water-soluble poly(oxazolines). The water-soluble poly(oxazoline) acts as a stabilizer for the cells and reduces the mechanical stress exerted by agitating the cell culture medium on the cells. This leads to an improved survival rate of the cells compared to the unstabilized state.
