Abstract

Rubber mixtures, including at least one rubber, a filler, an organosilicon compound of the formula Ione rubber accelerator and one co-accelerator. The rubber mixtures are prepared by mixing at least one rubber, a filler, an organosilicon compound of the formula I, one rubber accelerator and one co-accelerator. The rubber mixtures can be used for production of moldings. Also disclosed is a process for preparation of the organosilicon compound of the formula I via transesterification.
