Abstract:
The present invention relates to microparticulate materials comprising nanoparticulate cores of inorganic material with oligomeric or polymeric structures containing non-acidic, nucleophilic groups on their surface, where the cores have been agglomerated via an interaction of the non-acidic, nucleophilic groups with at least one further constituent containing electrophilic groups. The present invention furthermore relates to catalysts built up from these materials, to processes for the production of these materials or catalysts, to the use of the catalysts for the polymerisation of olefins, and to a polymerisation process using the catalysts.
Abstract:
The present invention relates to binders, to processes for the preparation thereof, and to the use thereof in formulations, surface coatings, inks and plastics.
Abstract:
The invention relates to particles which have been functionalised by means of an inertised reactive group, i.e. by means of specific reversibly blocked isocyanate groups, and whose inertisation can be reversed by means of an external influence.
Abstract:
The invention relates to spiro compounds of the formula (I) and to monolithic materials prepared therefrom by twin ring-opening polymerisation which consist of a porous metal oxide or semimetal oxide framework and are suitable for use as catalyst supports or as supports for active compounds.
Abstract:
A connecting device for connecting a hose in a fluid-conveying system including a nipple and a compression sleeve. The nipple has a rotation-symmetrical hose-receiving section and, at a distance therefrom, an anti-twist section that is configured in a non-circular manner, at least after a connection has been established between said hose and the nipple. The compression sleeve is configured to extend over the hose-receiving section and over the anti-twist section. The compression sleeve is further configured for a positive-locking engagement with respect to a relative rotation in the anti-twist section. The anti-twist section is configured as a non-circular deformation of at least part of the nipple. A method for establishing an anti-twist connection between a nipple and a hose using a compression sleeve is also disclosed.
Abstract:
A method is provided for producing a smart card comprising a chip module with at least one contacting area, the chip module arrangeable in a mounting location of a substrate, wherein one contacting loop is formed from a wire connector fed by a wire guiding unit for at least one of the contacting areas, respectively by attaching a first section of the wire conductor to a surface of the substrate outside the mounting location, wherein a second section of the wire conductor proximate to the first section is guided to form the contacting loop along with and protruding from the surface, wherein a subsequent third section of the wire conductor is attached to the surface outside the mounting location, wherein the chip module is inserted into the mounting location and wherein the second section is bent over and electrically contacted to the contacting area.
Abstract:
The present invention relates to a polysiloxane of the general formula (I) having at least one epoxidic radical and at least one quaternary nitrogen atom and also a textile auxiliary which comprises at least one polysiloxane according to the present invention. The polysiloxane is capable of crosslinking with or on the fiber.
Abstract:
The invention relates to a method and coating agents used in the method which provide good adherence to and good corrosion protection of metal substrates; the coating coating agents are cross-linkable via radical polymerization. Adhesion promoting compounds are present in the conversion layer in a quantity of about 0.01 to 40 weight percent and contain, on average, one reactive unsaturated group and at least one H-active group per molecule.
Abstract:
