HOMOOLIGOPHENOLFORMALDEHYDE PHTHALIDE-CONTAINING NOVOLAC BASED ON 3,3-BIS(4'-HYDROXYPHENYL)PHTHALIDE AS OLIGOMER FOR PRODUCTION CROSS-LINKED POLYMERS AND WAY OF ITS PRODUCTION, COOLIGOPHENOLFORMALDEHYDE PHTHALIDE-CONTAINING NOVOLACS BASED ON 3,3-BIS(4'-HYDROXYPHENYL)PHTHALIDE AND OHENOL AS COOLYGOMERS FOR PRODUCTION OF CROSS-LINKED PHTHALIDE-CONTAINING COPOLYMERS, WAT OF THEIR PRODUCTION AND CROSS-LINKED PHTHALIDE-CONTAINING COPOLYMERS Russian patent published in 2012 - IPC C08G8/24 

FIELD: industrial chemistry.

SUBSTANCE: invention refers to homo- and coolygophenolformaldehyde phthalide-containing novolacs based on 3,3-bis(4'-hydroxyohenyl)phthalide, cooligomers for production of cross-linked phthalide-containing copolymers, their production method and cross-linked phthalide-containing copolymers based on them that are solidified by the compounds containing hydroxymethyl groups (hydroxymethyl derivatives of phenols, phenolformaldehyde resols), and by urotropine. The homoolygophenolformaldehyde phthalide-containing novolac is manufactured on the basis of 3,3-bis(4'-hydroxyohenyl)phthalide with the general formula where n=2-4 as an oligomer for production of cross-linked phthalide-containing copolymers.

EFFECT: production of homo- and cooligophenolformaldehyde phthalide-containing novolacs that are stable in the course of synthesis, in storage and processing, and development of their production methods, and production of the cross-linked phthalide-containing copolymers that are promising from the point of view of heat-resisting and electroactive materials creation.
