摘要： Modified perfluoroplastics and method for the production thereof. The invention relates to the field of chemistry and relates to modified perfluoroplastics that can be used, for example, in tribomaterials, and a method for the production thereof. Modified perfluoroplastics which, when processed in structural parts, lead to comparable gliding properties and improved wear resistances, and furthermore there is provided a simple and efficient method for production thereof. Modified perfluoropolymers are provided, the surface of which simultaneously exhibit -COOH and/or COF groups and reactive perfluoroalkyl-(peroxy-) radical centers, whereby further low-molecular and/or oligomeric and/or polymeric substances and/or olefinically unsaturated monomers and/or oligomers and/or polymers are coupled via the groups and/or to the centers. There is also provided a method for producing modified perfluoroplastics in which modified perfluoropolymers, which simultaneously exhibit -COOH and/or -COF groups and reactive perfluoroalkyl-(peroxy-) radical centers, are reacted with other substances through substitution reactions and/or addition reactions and/or radical reactions.

摘要： Die Erfindung bezieht sich auf das Gebiet der Chemie und betrifft chemisch gekoppelte PVC-Perfluorpolymer-Materialien, wie sie beispielsweise für Anwendungsgebiete mit tribologischen Anforderungen im Maschinenbau (speziell für Geräte- und Gehäusebau) eingesetzt werden. Aufgabe der vorliegenden Erfindung ist es, ein chemisch gekoppeltes PVC-Perfluorpolymer-Material anzugeben, welches verbesserte tribologische Eigenschaften, insbesondere hinsichtlich Gleitreibung und Verschleiß, aufweist. Die Aufgabe wird gelöst durch ein chemisch gekoppeltes PVC-Perfluorpolymer-Material, bestehend aus modifizierten Perfluorpolymer-Pulverpartikeln, an deren Oberfläche PVC in Schmelze über eine reaktive Umsetzung chemisch über kovalente Bindungen gekoppelt ist. Die Aufgabe wird weiterhin gelöst durch ein Verfahren zur Herstellung von chemisch gekoppelten PVC-Perfluorpolymer-Materialien, bei dem Perfluorpolymer-Pulver mit reaktiven Perfluoralkyl-(peroxy-)radikalen und/oder funktionellen Gruppen in Form von Carboxylatgruppen und/oder von Carbonsäurefluorid- und/oder Carbonsäuregruppen, die vor oder während der reaktiven Umsetzung aktiviert werden, in Schmelze mindestens zusammen mit PVC reaktiv umgesetzt wird.

摘要： The invention relates to the field of chemistry and relates to long-term stable oil PTFE dispersions, such as can be used, for example, in transmissions or bearings, and a method for the production thereof. The object of the present invention is therefore to disclose a long-term stable oil PTFE dispersion as well as a simple and cost-effective method for the production thereof. The object is attained with an oil PTFE dispersion comprising PTFE particles and a monoolefinically or polyolefinically unsaturated oil, wherein molecules of the olefinically unsaturated oil are covalently/chemically coupled to PTFE (primary) particle surfaces via radical reactions, and wherein a permanent charge separation between the PTFE particle surfaces and the coupled oil molecules is present and a fine dispersion of the PTFE particles in the oil or oil mixture is present. The object is furthermore attained through a method in which the modified PTFE (emulsion) polymers are mixed with persistent perfluoro (peroxy) radicals jointly with an olefinically unsaturated oil and subsequently the modified PTFE (emulsion) polymers are subjected to a mechanical stress.

摘要： The invention refers to the area of materials science and relates to a material-plastic composite as can be applied as composites in functional parts, for example. The object of the present invention is to provide material-plastic composites that provide an integral direct composite by way of adhesive and above all covalent bonds. The object is accomplished through material-plastic composites comprised of at least one material component and at least one elastic plastic composite, wherein the material component is coated with at least one (partially) cross-linked enamel, the re(active) and/or activatable groups thereof that have functional groups or the functional groups thereof that have re(active) and/or activatable groups of elastic plastic components having covalent bonds. The object is further accomplished by a method for manufacturing material-plastic composites in which a coating of a (partially) cross-linkable enamel is applied to at least one material component, followed by at least one elastic plastic component being at least partially applied to the enamel coating layer by way of a thermal application method.

摘要： The invention refers to the field of chemistry and relates to a method, whereby the plastic surfaces have, for example, an improved adherence or anti-adherence. The aim of the invention is to specify an easily manageable method for activating or passivating the plastic surfaces. To this end, the invention provides a method for modifying plastic surfaces, according to which the plastic surfaces are modified during or immediately after a shaping process or are modified after a shaping process, and the temperature of the plastic surface is at least the onset temperature of the reaction peak in the DSC curve. In addition, one or more modifying substance(s) is/are entirely or partially brought into contact with the surface of the shaped plastics. Substances used as the modifying substance(s) are substances of the type that react with the surface of the shaped plastic and/or penetrate into the surface by interdiffusion and/or melt onto the surface.
