NOVEL N-PHENYL P-PHENYLENE DIAMINO DERIVATIVES AND THEIR USE AS STABILIZER IN RUBBER OR RUBBER LATEX

摘要

There are disclosed novel compounds of the formula: wherein n=0 or 1, R1 is selected from the group consisting of a hydrogen atom, straight chain and branched chain alkyl groups and alkoxy groups, and cycloalkyl groups and cycloalkoxy groups having 5 to 8 carbon atoms, R2 is selected from the group consisting of lower alkyl groups having 1 to 5 carbon atoms, X is an oxygen atom if n=0 or a nitrogen atom if n=1, Y is selected from the group consisting of a hydrogen atom, straight chain and branched chain alkyl groups having 1 to 18 carbon atoms, cycloalkyl groups having 5 to 8 carbon atoms, alkenyl groups having 3 to 18 carbon atoms, phenyl groups, alkylphenyl groups having 7 to 14 carbon atoms and aralkyl groups having 7 to 15 carbon atoms, and R3 is selected from the same group as Y, or together with X and Y forms part of a heterocycle ring composed of 5 or 6 atoms in which X is the hetero-nitrogen atom. Also disclosed is the use of the foregoing compounds as stabilizers in rubber or rubber latex.
