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 positions ortho to at least one of the —O—Z groups being unsubstituted, is used for the manufacture of a phenol-aldehyde resin for reinforcing a rubber composition. Each —O—Z group represents an —O—Si(R1R2R3) group with R1, R2, R3 representing, independently of one another, a hydrocarbon-based radical or a substituted hydrocarbon-based radical.
一种芳香族多酚衍生物包含至少一个芳香环,该芳香环上至少有两个-O-Z 基团,这两个-O-Z 基团在相对于彼此的元位置上,其中至少一个-O-Z 基团的两个正交位置是未被取代的,该衍生物可用于制造酚醛树脂,以增强橡胶组合物。每个 -O-Z 基团代表一个 -O-Si(R1R2R3)基团,其中 R1、R2、R3 各自代表一个烃基或一个取代的烃基。
