Abstract
The present invention relates to a process for the production of rubber mixtures containing 1 to 500 parts by weight of one or more water-repellent fillers with a methanol wettability of .gtoreq.5 wt. % to 100 parts by weight of rubber, characterized in that said water-repellent fillers are blended with one or more rubber latices and the mixture is then processes jointly, and also to rubber mixtures that can be produced with this process. The present invention relates furthermore to the use of the rubber mixtures produced by the process according to the invention for the production of tires, treads or molded articles of all kinds.
