By the use of special cross-linkers that contain at least two isocyanate groups, hydroxyl group-containing optionally hydrogenated nitrile rubber polymers can be successfully cross-linked. Preferred cross-linkers contain allophanate, biuret, uretdione, uretonimine, bridged carbamate, carbodiimide, isocyanurate, iminooxadiazinedione or oxadiazinetrione structural elements.

Compositions that can be vulcanized and that are based on ethylene/vinyl acetate copolymers containing epoxy groups

The invention relates to vulcanizable compositions based on carboxylated nitrile rubbers, at least one resol crosslinker, at least one silicatic filler and at least one specific silane, to a process for preparing these vulcanizable compositions, to a process for producing vulcanizates therefrom and to the vulcanizates thus obtained. The vulcanizates feature good mechanical and dynamic properties and an excellent compression set.

There are provided novel vulcanizable compositions based on optionally fully or partly hydrogenated nitrile rubbers containing epoxy groups, and specific crosslinkers, which no longer require use of conventional crosslinkers, more particularly sulphur. The vulcanizates producible therefrom possess very good compression sets at room temperature, 100&#xb0; C. and 150&#xb0; C., and additionally exhibit high tensile stress combined with good elongation at break.

Compositions that can be vulcanized and that are based on nitrile rubbers containing epoxy groups

There are provided novel vulcanizable compositions based on optionally fully or partly hydrogenated nitrile rubbers containing epoxy groups, specific basic crosslinkers and crosslinking accelerators, as a result of which the use of conventional crosslinkers, such as sulphur in particular, is no longer required. The vulcanizates producible therefrom possess very good compression sets at room temperature, 100&#xb0; C. and 150&#xb0; C., and additionally exhibit high tensile stress combined with good elongation at break.

Vulcanisable compositions based on epoxy group-containing nitrile rubbers

There are provided novel vulcanizable compositions based on optionally fully or partly hydrogenated nitrile rubbers containing epoxy groups, and specific crosslinkers, which no longer require use of conventional crosslinkers, more particularly sulphur. The vulcanizates producible therefrom possess very good compression sets at room temperature, 100&#xb0; C. and 150&#xb0; C., and additionally exhibit high tensile strength combined with good elongation at break.

Vulcanizable compositions based on nitrile rubbers containing epoxy groups

An improved polymerization process using a specific molecular weight regulator makes it possible to produce new nitrile rubbers featuring particularly low emission values and giving vulcanizates which have an advantageous profile of properties and which are of outstanding quality, in particular in odor-sensitive applications.

Nitrile rubbers having low emission values

Polymer vulcanizate and process for the production thereof

Through the use of an improved iron-based redox system it is possible to prepare special new, optionally hydrogenated, nitrile rubbers which feature a more uniform monomer distribution and a lower fraction of long-chain branches and hence are distinguished by enhanced flow properties at the same time as very good properties on processing.

Nitrile rubbers

Novel crosslinkable compositions based on elastomers, at least one of which has carboxyl and/or carboxylate groups, are provided, these crosslinkable compositions containing special unsaturated organic salts of metal ions and a crosslinking system which acts as a free radical donor. Crosslinked elastomers which have excellent physical properties are obtainable therefrom. The novel crosslinkable compositions have a wide range of uses.

Crosslinkable compositions, processes for the preparation thereof and the use thereof

The present invention relates to a process for reducing mold contamination in an injection molding process by using a mixture of nitrile rubbers, in the range of from 0.1-0.5 wt. % of fatty acids and optionally further additives.

Nitrile rubber mixtures with a low tendency towards mold contamination

This invention relates to a mixture containing one or more olefin rubbers and one or more nitrile rubbers, to a process for the production thereof, to a vulcanizable mixture and to a process for the production thereof as well as to moldings of all kinds producible from the mixtures.

Mixtures of olefin polymers and nitrile rubbers

This invention relates to mixtures of polychloroprene elastomers which are distinguished by their good processibility and excellent cold resistance.
