N,N1 - Bis(1,3,3, - trimethylbutyl) - p-phenylene diamine is used as an antiozonant for rubber. It may be incorporated in natural or synthetic rubbers particularly diene rubbers. It may be incorporated in unvulcanized rubber together with a vulcanizing agent, accelerator and other conventional additives and the resulting composition vulcanized by heating. The preferred amount of antiozonant used is 0.5-3.0% by weight of the rubber.ALSO:The invention comprises N,N1-bis(1,3,3-tri-methylbuthyl-p -phenylenediamine. It is prepared by the reductive alkylation of p-phenylenediamine, or a precursor of p-phenylenediamine capable of giving p-phenylenediamine on reduction, e.g. p-nitroaniline, with neopentyl ketone.ALSO:N,N/sv - Bis(1,3,3-trimethylbutyl)-p-phenylenediamine may be used to inhibit the germination of the fungal pathogen which causes apple scab. An example is given of the use of the compound in aqueous solution.
