The invention relates to methods for producing rubber mixtures containing microgels, rubber mixtures that can be obtained by such methods, methods for producing vulcanizates and vulcanizates that canbe obtained by the vulcanization method, particularly in the form of tires, tire parts or commercial rubber articles. The method for producing rubber mixtures mixes components as follows: a) one or more rubber components, b) one or more filers containing hydroxyl groups, c) one or more microgels containing hydroxyl groups, d) one or more organosilicon compounds containing sulphur, e) one or more curing agents in propriety, f) one or more rubber additives in propriety. The method is characterized in that: the organosilicon compounds containing sulphur d) is added by at least two separated parts, wherein, the first part comprises at least 30% of total amount of the organosilicon compounds containing sulphur by weight. The rubber mixtures are suitable for producing various tire components. |
