Abstract
The relative inhibitory effect of the following compounds on the bulk polymerization of methyl methacrylate were measured: hydroquinone, p-tert-butylcatechol, p-methoxyphenol, 2,4-dichloro-6-nitrophenol, n-propyl gallate, di-tert-butyl-p-cresol, 2,2'-methylenebis(4-methyl-6-tert-butylphenol), 1-amino-7-naphthol, p-benzoquinone, 2,6-dichloro-p-benzoquinone, 2-amino-1,4-naphthoquinone, three aminoanthraquinones, diphenylamine, p-nitrosodimethylaniline, α- and β-naphthylamine, phenothiazine, N-nitrosodimethylamine, hexamethylphosphoramide, n-dodecyl mercaptan, benzenethiol, 2,2-diphenyl-1-picrylhydrazyl, phenyl hydrazine, divinylacetylene, and various antimony and copper salts. Polymerization was carried out in a test tube in a bath at 101.2°C., benzoyl peroxide being used as initiator. Generally, phenols and naphthols were the strongest inhibitors, followed by quinones, aromatic amines, 2,2-diphenyl-1-picrylhydrazyl, antimony pentachloride, phenyl hydrazine, divinylacetylene, and the thiols.
