Abstract: This invention relates to a toner for electrophotography which develops an electrostatically charged image, the toner at least containing a coloring agent, a binder resin, a charge control agent, and a functioning agent, wherein low molecular weight polyolefin wax obtained by a metallocene type polymerization catalyst is contained as the function imparting agent. The toner of the invention is excellent in fixability, and has offset preventing properties, heat response characteristic, anti-spent toner properties, and storage stability, which can thus obtain a sharp, high quality image.

Abstract: The present invention relates to a composite material that contains 5 to 97%-vol aerogel particles and at least one adhesive and that is characterised in that the diameter of the aerogel particles is smaller than 0.5 mm, a process for manufacturing this, and the use thereof.

Abstract: The invention relates to polymers which form cholesteric phases, to a process for their preparation and to their use.Novel polymers and oligomers which form cholesteric phases essentially consist, as molecular building blocks, ofA. at least one bifunctional chiral molecular building block which contains at least one cyclic structural element other than a monosubstituted p-phenylene group,B. at least one bifunctional achiral or racemic molecular building block which contains at least one cyclic structural element containing at least four ring members, andC. at least one bifunctional molecular building block which can be either chiral or achiral, cyclic or acyclic, and is different from the molecular building blocks A and B actually employed,with the proviso that the molecular building block A is not derived exclusively from camphoric acid.
