High strength rubber composition
11091580 · 2021-08-17 · ·

A rubber composition comprises at least one resin based on: (A1) at least one aromatic compound resulting from the reaction between a reactant of formula (α): ##STR00001##
where B represents CHO or CH.sub.2OH, (α) and a reactant of formula (β) or ##STR00002##
and (A2) at least one phenolic compound chosen from: (A21) at least one aromatic polyphenol comprising at least one aromatic ring bearing at least two hydroxyl functional groups in the meta position with respect to one another, the two positions ortho to at least one of the hydroxyl functional groups being unsubstituted; and/or (A22) at least one aromatic monophenol comprising at least one six-membered aromatic ring bearing a single hydroxyl functional group, the two positions ortho to the hydroxyl functional group being unsubstituted or at least one position ortho to and the position para to the hydroxyl functional group being unsubstituted.
