Abstract: The present invention relates to a basically spherical hyperbranched block copolymer having an internal hydrophobic block and an external hydrophilic block. Within the spherical copolymer, the hydrophobic block constitutes a hydrophobic layer, suitable to associate or encapsulate hydrophobic bioactive agents, while the hydrophilic block provides an outer layer, which is suitable to render the copolymer soluble or dispersible in aqueous solutions. Also claimed is a method for preparing the copolymer, which is suitable to encapsulate fragrances, flavours, drugs, agrochemicals, for example.

Abstract: Compounds of the formula I according to claim 1 are excellently suitable as UV absorbers for use in cosmetic products, in particular sunscreen compositions, daytime care products and hair care products. They are furthermore suitable for protection of products.

Abstract: Compounds of the formula ##STR1## in which one of the radicals R.sup.1 and R.sup.2 is methyl and the other is vinyl and one of the radicals R.sup.3 and R.sup.4 is methyl and the other is ##STR2## in which R.sup.5 is hydrogen, alkyl or alkenyl, in particular C.sub.1 -C.sub.6 -alkyl or C.sub.2 -C.sub.6 -alkenyl, are particularly suitable as fragrances and flavors.

Abstract: Compounds which, per molecule, contain at least 2 benzazolyl groups are outstandingly suitable as UV absorbers for sunscreen compositions.

Abstract: A flat sealing plate for combustion engines and a method for manufacturing same are disclosed. The sealing plate comprises a layer of soft sealing material consisting of mineral base compounds as well as of a binder material being at least partially vulcanized. A first and a second metallic foil are glued on both sides of the soft sealing material layer. For the manufacture of such sealing plate calender rolls are used to calender the sealing material on the first foil and additional rollers are then used to laminate the second foil on the opposite side of the sealing material layer.

Abstract: A reinforced support sheet or plate, especially for making flat gaskets or heat dampening plates is made of a sheet or plate-like support material which is covered with a vulcanizable soft material layer which contains a fiber-like and, if need be, powder-like binder material. The support material is smooth and the soft layer material is composed predominantly of a powder-like, asbestos-free mineral base material. The mineral base material may include mostly a chemically and thermally untreated material and also a chemically and thermally or only thermally treated material. A method for making such a sheet or plate is also disclosed.
