The invention provides resin- and mineral oil-free pressure-sensitive adhesive compositions, comprising 55%-100% by weight of a copolymer of propylene and one or more further monomers selected from the group composed of ethylene and 1-olefins having 4 to 20 carbon atoms, wherein the copolymer has been prepared with the aid of metallocene catalysts and is characterized by

Permanently tacky adhesives with improved environmental compatibility

The invention relates to a hot-melt adhesive substance for sticking together fibrous materials such as matted nonwovens or woven textiles with smooth substrate surfaces, such as plastic or metal films, and for laminating said materials. Said substance is characterized in that it contains at least one polyolefin which has been produced by polymerization in the presence of metallocene as a catalyst and has a ring/ball softening point of between 50 and 165&#xb0; C. and a melting viscosity, measured at a temperature of 170&#xb0; C., of between 20 and 40,000 mPa-s. The hot-melt adhesive substance can also contain at least one adhesive component and is used in a quantity of between 3 and 6 g/m, preferably between 4 and 5.5 g/m, for sticking a film to a nonwoven material during the production of hygiene items such as disposable nappies, baby nappies, incontinence products, panty liners and/or sanitary towels.

Hot-melt adhesive substance

The invention provides polar-modified rice husk waxes obtainable by free-radical grafting of unmodified rice husk waxes with graft comonomers selected from the group of the &#x3b1;,&#x3b2;-unsaturated mono- or polybasic carboxylic acids or derivatives thereof. The invention further provides derivatization products prepared by chemical conversion of the polar-modified rice husk waxes of the invention. The invention further provides processes for producing the products of the invention and for the use thereof.

Polar-modified rice husk wax

The invention relates to a printing ink system containing glycosidic polymers and polyolefin- and/or Fischer-Tropsch-waxes and/or amide waxes and/or bio-based waxes and optionally pigments, binders and/or solvents. The glycosidic polymer has a specific surface area according to BET from a minimum 0.45 m2/g and a particle size distribution having an uniformity coefficient (D60/D10) to a maximum of 3.5.

Printing ink systems

The invention relates to waxy oxidation products of rice bran, which are characterized by an acid number measured according to DIN ISO 2114 of at least 70 mg KOH/g, preferably at least 100 mg KOH/g, most preferably at least 140 mg KOH/g, and their use for producing synthetic ester waxes by esterification with one or more mono- or polyvalent alcohols.

Waxy oxidation products of rice bran

The invention relates to a solvent-based separation method for the total material recycling of materials used in nonwoven, woven, and tufted wares into the individual material components thereof sorted by type. At least one of the materials contains a polyolefin wax. As a solvent and/or swelling agent, halogen-free, aliphatic hydrocarbons or aromatic hydrocarbons or a mixture of one or several of said solvents are used.
