FIELD: polymerization processes.
SUBSTANCE: invention relates to technology of producing polyphenylene exhibiting antihypoxant, antioxidant, and antiradical properties. Polyphenylene is obtained via polymerization of hydroquinone preliminarily dissolved in water or in alcohol solution. Polymerization process involves use of hydrogen peroxide, which is added in presence of aqueous solutions of Period IV transition metal salts, preferably Cr, Mn, Fe, Cu, Ni, Co, and Zn salts hydrates. Temperature is controlled not to exceed boiling temperature and pH is controlled within 2 to 7. Polymerization is effected with hydroquinone concentration in water 10-20%.
EFFECT: reduced toxicity of product.
