Abstract (en)

[origin: WO2023274907A1] The new organosilyl polysulfides of formula (I), in which substituents R1 to R8 and index x have the meanings indicated in the description, are extremely well suited for the manufacturing of rubber mixtures having improved mixing properties, vulcanized products and rubber products which can be obtained therefrom and which are characterized by greater hardness, strength and elongation at break as well as low rolling resistance of the tires made therefrom.
