4,5-Dihydro-4,4-dimethyl-2,3-dithioloquinoline-1-thiones and gossypol are effective antioxidants in the polymerization of vinyl monomers.Kinetic parameters of inhibition reactions depend on the structure of the monomer and inhibitor and the nature of the initiator.A mechanism is proposed for the reaction of peroxy radicals with sulfur-containing hydroquinolines.

The inhibiting effect of dithiolthione derivatives of hydrogenated quinolines (DTT) on the oxidation of various hydrocarbons (n-decane, n-decene, ethylbenzene, β-carotene) was investigated.The inhibiting effect of the DTTs is greater at high temperatures (>100 deg C) than that of the parent hydrogenated quinolines and weaker at moderate temperatures.The DTTs do not affect the decomposition of hydroperoxides.Probably, the introduction of a dithiothione cycle to a hydroquinoline molecule decreases its reactivity toward O2 and peroxide radicals, which favors the enhancement of the antioxidative activity of the DTTs at elevated temperatures. - Key words: hydrogenated quinolines, dithiothione derivatives; n-decane, n-decene, ethylbenzene, β-carotene, inhibited oxidation.
