Chemical Name:  Polymerized 2,2,4 – trimethyl – 1,2 – dihydroquinoline
Synonyms:  1,2-Dihydro-2,2,4-trimethylquinoline oligomers, Acetonanil, Acetonanyl, Acetone Anil, DHMQ, Hydro-2,2,4-trimethylquinoline oligomers, Poly(1,2-dihydro-2,2,4-trimethylquinoline), Polymerized 1,2-Dihydro-2,2,4-trimethylquinoline, TDQ, TMDQ, TMQ, Trimethyldihydroquinoline polymer.
CAS No.:  26780-96-1
H.S. Code:  3812.30.2000
Main applications: 
  • Slightly staining non-blooming antioxidant in the production of rubber compounds for tyres, tyres retreads and heavily stressed technical rubber goods (tubes, buffers, insulating electric wires & cables, conveyor and transmission belts, steam hoses, break linings, oil seals, profiles, boots and footwear soles and heels) based on NR, IR, SBR, NBR and polybutadiene. 0.5 - 3.0 phr loadings enhance their flex life and provide long-time thermal-oxidative protection.
  • Excellent antiozonant for CR, partially replaces para-phenylenediamine (PPDA) antiozonants.
  • Inhibitor of oxidation catalyzed by copper and manganese.

Other applications:

  • Peroxide cure (0.25 - 1.0 phr) of EPR/EPDM and NBR compounds.
  • Antioxidant protection of latexes.
