Methylol derivative on the basis of 2,2-bis-(4-oxyphenyl) adamantane was obtained. Some kinematic regularities of reaction of interaction of 2,2-bis-(4-oxyphenyl) adamantane and formaldehyde were studied at 115-130°C, in n-propyl alcohol, in the presence of ammonia, as the catalyst, at an initial bis-phenol-formaldehyde molar ratio of 1:4. It was proved that the reaction proceeded according to the second order. Activation energy and reaction rate constants were calculated. The effect of various factors on the process of reaction was investigated. IR-spectroscopy was used to study the process of thermal hardening of methylol derivative of 2,2-bis-(4-oxy phenyl) adamantane, at isothermal terms, on air, at 115, 200, 250 and 300°C. Thermogravimetric and thermomechanical investigations of resite, formed at thermal hardening of methylol derivative of bis-phenol were carried out. When heated at a temperature exceeding destruction one, adamantane-containing resite was decomposed without formation of coke residuum. Source
