  • Patent number: 8883931
    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.

  • Publication number: 20130018140
    Abstract: The invention relates to N-bridged polynitrons and their use for cross-linking of unsaturated polymers, as well as a curable composition comprising (a) a N-bridged polynitron, (b) an unsaturated polymer or a mixture of polymers, wherein at least one unsaturated polymer contains unsaturated functions or functional groups which can react with the polynitron, (c) optionally fillers, (d) optionally pigments, (e) optionally additives such as plasticizers, stabilizers, photoinitiators, and (f) optionally, other cross-linking agents such as polyisocyanates, bisdienes, polyoxaziridines, and their use as adhesives, rubber, filling, sprayable thick-layer filler, ink, paint, powder paint, waterborne paint or solvent based paint. Further, the invention relates to cross-linking products obtainable by curing the curable composition according to the present invention.
