  • Adhesive composition for bonding rubber to metal
    Patent number: 10975271
    Abstract: An adhesive composition is comprised of a film forming polymer, (ii) a lower crystallinity polynitroso compound, (e.g., poly-(1,4-phenylyenazine-N,N-dioxide)), (iii) a higher crystallinity polynitroso compound (e.g., poly-(1,4-phenylyenazine-N,N-dioxide)), and (iv) a carrier liquid. The composition is useful in bonding metal and rubber to make, for example, components to damp noise, vibration or harshness.

  • Method for producing poly-(1,4-phenylenazine-N,N-dioxide) by oxidizing p-benzoquinonedoxime
    Patent number: 6600005
    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.
