摘要

A rubber mixture comprising at least one polymer base with a cross- linkable unsaturated chain, a vulcanization system, and antioxidant agents comprising in monomer form one or more compounds covered by the general formula ( I) wherein, the substituents R1, R2, R3, R4 and R10, which are equal to or different from one another, are chosen among H, OH, and (CH2)nCHCH2 with n as an integer number ranging from 1 to 10; provided that, among the substituents R1, R2, R3, R4 and R10, at least one is OH and at least one is (CH2) nCHCH2; and the substituents R5, R6, R7, R8 and R9, which are equal to or different from one another, are chosen among H, OH, and (CH2)nCHCH2 with n as an integer number ranging from 1 to 10; provided that, among the substituents R5, R6, R7, R8 and R9, at least one is OH and at least one is (CH2) nCHCH2.
