HOMOOLIGOPHENOLFORMALDEHYDE NOVOLAC BASED ON 2-(β-HYDROXYETHYL)-3,3-BIS-(4'-HYDROXYPHENYL)PHTHALIMIDINE FOR OBTAINING PHTHALIMIDINE-CONTAINING CROSS-LINKED POLYMERS AND METHOD OF ITS OBTAINING, COOLIGOPHENOLFORMALDEHYDE NOVOLACS BASED ON 2-(β-HYDROXYETHYL)-3,3BIS-(4'-HYDROXYPHENYL)PHTHALIMIDINE FOR OBTAINING CROSS-LINKED PHTHALIMIDINE-CONTAINING COPOLYMERS, METHOD OF THEIR OBTAINING AND CROSS-LINKED PHTHALIMIDINE-CONTAINING COPOLYMERS AS CONSTRUCTION POLYMERS Russian patent published in 2014 - IPC C08G8/00 C08G8/24 

FIELD: chemistry.

SUBSTANCE: invention relates to homo- and cooligophenolformaldehyde phthalimidine-containing novolacs based on 2-(β-hydroxyethyl) 3,3-bis(4'-hydroxyphenyl)phthalimidine, stable in the process of production, storage and processing, as well as to a method of their obtaining. In the process of solidification of novolacs with urotropin, as well as compounds, which contain hydroxymethyl groups (hydroxymethyl compounds of phenols, phenolformaldehyde resoles) obtained are cross-linked phthalimidine-containing copolymers with high strength parameters (transverse rupture stress and specific impact strength reaches values of 69.0 mPa and 3.4 kJ respectively) and thermal characteristics (temperatures, at which 10 and 20% loss is observed, reach values of 430 and 490°C respectively).

EFFECT: obtaining cross-linked cooligophenolformaldehyde phthalimidine-containing copolymers, used in creation of thermally stable construction polymer materials with high strength parameters.
