Abstract

The invention relates to rubber mixtures which contain microgels and isocyanatosilanes and vulcanisates produced therefrom. By adding isocyanatosilanes the mechanical properties of the vulcanisates, in particular the elongation properties and the abrasion resistance, are improved without the difference in rebound resilience at 70° C. and 23° C. being reduced.
