There are disclosed novel compounds of the general formula:
wherein n = 0 or 1, and R, represents a hydrogen atom, a straight chain or branched chain alkyl group or alkoxy group having not more than 10 carbon atoms, a cycloalkyl group or cycloalkoxy group having 5 to 8 carbon atoms, R2 a lower alkyl group having 1 to 5 carbon atoms, X an oxygen atom if n = 0 or a nitrogen atom if n = 1, Y represents a substituted or unsubstituted straight chain or branched chain alkyl group having 1 to 18 carbon atoms, a substituted or unsubstituted cycloalkyl group having 5 to 8 carbon atoms, an alkenyl group having 3 to 18 carbon atoms, a substituted or unsubstituted phenyl group, an alkylphenyl group having 7 to 14 carbon atoms or an aralkyl group having 7 to 15 carbon atoms, and R, may have the same meaning as Y. or represents a hydrogen atom, or together with Y may form part of a heterocyclic ring composed of 5 or 6 atoms. Also disclosed is the use of the foregoing compounds as stabilizers in rubber or rubber latex.
