    摘要: 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(RO).sub.3 Si--Y--S.sub.x --Y--Si(OR).sub.3wherein R, Y and x are defined herein, or a mixture of an oligosulfane of this formula (main product) and of a structurally related, substantially dimeric condensation product, which is characterized by a siloxane bond (by-product).
