Abstract: The invention relates to a method for producing poly(1,4-phenylenazine-N,N-dioxide) and derivatives thereof which are substituted in the ring, by oxidizing p-benzoquinonedioxime or the corresponding derivative thereof which is substituted in the ring, using polyanions of the halogens bromine or iodine. Tribromide Br3- or triiodide I3- can be used as polyanions and these can be obtained in situ from H2O2 and a bromide or iodide.

Abstract: A water-based adhesive is disclosed which contains an aqueous dispersion of one or more phenol resins stabilized by one or more polyacrylates, one or more latexes with one or more halogenated polyolefins and one or more cross-linking agents. The invention also includes a method of priming a substrate in which the substrate is coated with the adhesive as a primer and then with a cover cement and finally bonded to rubber under vulcanization.

Abstract: A bonding composition comprising an aqueous dispersion is described, which is used to bond natural and synthetic elastomers to metallic and nonmetallic substrates under vulcanizing conditions. Such dispersions contain an organic polymeric film-forming substance, an aromatic polynitroso compound, and a coactivator and optionally contain conventional adhesion promoters, fillers and processing aids. In order to widen the field of application and to ensure a high stability of the bond against corrosive influences, the coactivator particularly consists of phenylene bis-maleic acid imide, but one more of the following may be used: triallyl- cyanurate, triallylisocyanurate, diallylacrylamide, tetraallylterephthalamide, tris(1-methyl-2-propenyl) isocyanurate, trivinylisocyanurate, triallyltrimellitate, diallylphthalate, ethylene-glycoldimethacrylate, trimethylolpropanetrimethacrylate, and 1,3-butyleneglycoldimethacrylate.
