USE OF A SILYLATED AROMATIC POLYPHENOL DERIVATIVE FOR THE PRODUCTION OF A PHENOL-ALDEHYDE RESIN FOR REINFORCEMENT OF A RUBBER COMPOSITION

摘要

The invention relates to the use of an aromatic polyphenol derivative comprising at least one aromatic ring bearing at least two -O-Z groups in the meta position relative to one another, the two ortho-positions of at least one of the -O-Z groups being non-substituted, for the production of a phenol-aldehyde resin for reinforcement of a rubber composition. Each -O-Z group represents an -O-Si(R1R2R3) group with R1, R2, R3representing, independently of one another, a hydrocarbon radical or a substituted hydrocarbon radical.
