ABSTRACT:
Novel adhesion promoters having, on the one hand, groups capable of forming a stable chemical bond with the surface of silicic acids and silicates (siloxane bond) and, on the other hand, groups capable of forming, during vulcanization, a stable chemical bond with an elastomer (sulfur bridges) are provided. They are consequently suitable as adhesion promoters for the production of vulcanizates exhibiting a favorable filler/elastomer bond. They are oligosulfanes of the formula
