Suitable anti-oxidants are (1) phenolic compounds such as phenol; alkyl phenols, e.g. 2, 4-dimethyl-6-tert. butyl-phenol and 2, 6-ditert. butyl-4-methyl phenol; alkyl alkoxy phenols, e.g. 2-tert. butyl-4-ethoxy phenol; a -naphthol; dihydroxy naphthalenes, e.g. 1, 5-and 1, 7-dihydroxynaphthalenes and the monoalkylethers thereof; 1-hydroxy-4-methoxy-7-methyl-5, 8-dihydronaphthalene; catechol and alkyl catechol including nordihydroguiairetic acid; dihydroxybenzenes, e.g. hydroquinone, and alkyldihydroxybenzenes and monoalkylethers thereof, e.g. 2-tert. butyl-4-methoxy phenol; trihydroxy benzenes, e.g. pyrogallol and alkylpyrogallols; alkyl gallates; 2, 2-dimethyl-5-hydroxy-6-tert. butyl coumaran; and 2, 2-dimethy -6-hydroxy-7-tert. butyl chroman; and (2) p-substituted-anilines and -N-alkylanilines, e.g. p-amino-anilines, p-hydroxyanilines, p-sec. butylamino-N-sec. butylaniline, p-hydroxy-N-methylaniline, p-n-butyl-amino-N-n-butyl aniline and o-methyl-p-sec. butyl-amino-N-sec. butylaniline.  Mixtures may be used, in particular p-n-butyl aminophenol and N, N1-di-n-butyl-p-phenylenediamine.  Polymerization may be effected in batch or, preferably, by a continuous operation.  The reactor in this case may be unpacked or it may contain adsorbent material such as fire brick, alumina, or dehydrated bauxite.  The charge may also be passed upwardly through adsorbent material, portions of which are continuously removed, cooled and returned. Suitable catalysts are peracetic acid, diacetyl peroxide, toluic acid peroxide, oleic peroxide, benzoyl peroxide, tert. butyl perbenzoate, ditert. butyl peroxide, hexyl peroxide, tert. butyl hydroperoxide and methyl cyclohexyl hydroperoxide.  The catalyst may be formed in situ when the diluent is hydrocarbon by heating the diluent, which may contain a minor amount of an olefinic hydrocarbon, while air is bubbled through it, preferably in the presence of a trace of a peroxy compound, or in the presence of an oxidation catalyst, e.g. manganese stearate, without heat.  In continuous operation, the catalyst may be added continuously or intermittently.  The anti-oxidant is generally used in less amount than catalyst, and is preferably in the ratio of 1 : 10. Specified diluents are benzene, toluene, ethyl benzenes, xylenes, tert. butyl alcohol, n-butane, isobutane, cyclohexane and methyl cyclohexane.  The polymers produced are waxy.
