Abstract: The present invention relates to the use of rubber mixtures containing copolymers based on an unsaturated olefinic nitrile, a conjugated diene and optionally a polymerizable carboxylic acid, at least one non-polar rubber and at least one polar synthetic plasticizer for the production of tires.

Abstract: The present invention relates to rubber mixtures containing at least one quaternary polymer and at least one polar synthetic plasticizer, to a process for their production and to their use in the production of rubber molded bodies.

Abstract: The present invention concerns rubber compounds containing at least one NSBR terpolymer and at least one polar synthetic plasticizer, a process for their production and their use to produce rubber moldings of all types.

Abstract: The invention relates to rubber mixtures containing a terpolymer (NSBR) based on an unsaturated olefinic nitrile, a vinyl aromatic compound and a conjugated diene, a non-polar rubber and a special mineral oil. The rubber mixtures according to the present invention have, in particular, an improved wet-skid behavior compared to rubber mixtures to which the conventional aromatic mineral oils have been added.

Abstract: The present invention provides rubber mixtures which contain at least one NSBR terpolymer and at least one polar synthetic plasticizer, a process for the preparation thereof and their use to produce rubber molded items of all kinds.

Abstract: The invention relates to quaternary polymers, based on conjugate dienes, vinyl-substituted aromatic compounds, olefinically unsaturated nitriles and amino group-containing monomers. The rubber vulcanizates or molded articles, in particular tires, produced from the quaternary polymers or their mixtures with other rubbers are balanced out by good mechanical properties, in particular by a desirable balance in relation to the rolling resistance, skid resistance in the wet and abrasion, which is of particular advantage in tire construction.

Abstract: The invention relates to quaterpolymers based on conjugated dienes, vinyl-substituted aromatic compounds, olefinically unsaturated nitrites and monomers containing hydroxyl or epoxy groups. The rubber vulcanized products or molded parts, in particular tires, produced from the quaterpolymers and/or their mixtures with other rubbers are characterized by good mechanical properties, in particular by a favorable balance as regards the rolling resistance, antiskid resistance in the wet, and abrasion resistance, which is particularly advantageous for example, in tire manufacture.
