Abstract HOE 89/F 136 Polymers which contain units of 4-hydroxystyrene and/or of 4-acetoxystyrene, where appropriate in a mixture with other comonomer units, in particular butadiene, can be used in place of phenolic or resorcinol resins as reinforcing resins and adhesion promoters in rubber mixtures. These polymers are distinguished by the fact that, coupled with at least equally good effectiveness, they do not release any phenolic materials into the environment on incorporation into rubber mixtures.
