    Abstract: The invention relates to modified polysaccharide ethers having a weight-averaged molecular weight of 40,000 to 500,000 g/mole, zero shear viscosity of more than 10 Pa·s, and pseudo-plasticity of more than 20. These modified polysaccharide ethers are obtainable by reacting cellulose-based polysaccharide ether(s) with at least one mesogenic modification agent or modified polysaccharide ethers, obtainable by reacting polysaccharide ether(s) selected from hydroxypropylmethyl cellulose (HPMC), hydroxyethylmethyl cellulose (HEMC), methyl cellulose, and cellulose ethers with methyl and/or ethyl and/or propyl groups and mixtures thereof, with at least one mesogenic modification agent. These substances can be used to produce gel-like to stable aqueous preparations having viscoelastic flow properties, which are suited for use in the human body, particularly within the scope of ophthalmologic procedures.

    Abstract: The present invention relates to polyfunctional nitrones (optionally in the form of nitrone-terminated polymers) and to their use as crosslinking agents and matting agents, preferably for producing stable molding compounds, knifing fillers, and use thereof in inks, coatings, and adhesives. Low crosslinking temperatures characterize the invention. Through the use of polyfunctional nitrones it is possible for all unsaturated polymers to be cured, solidified and/or structured at low temperatures, preferably without use of a catalyst. Depending on the amount of nitrone-terminated polymers and/or low molecular mass polyfunctional nitrone used it is possible to exert a strong influence over the optical and the mechanical properties of the coated surfaces. By optical properties are meant, among others, the gloss of the coating systems and the surface structuring, e.g., the matte effect.
