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.
