COOLIGOPHENOLFORMALDEHYDE PHTHALIDE-CONTAINING NOVOLACS BASED ON 3-PHENYL-3-(4'-HYDROXYPHENYL)PHTHALIDE AND PHENOL AS COOLIGOMERS FOR PRODUCTION OF CROSS-LINKED PHTHALIDE-CONTAINING COPOLYMERS, WAY OF THEIR PRODUCTION AND CROSS-LINKED PHTHALIDE-CONTAINING COPOLYMERS Russian patent published in 2012 - IPC C08G8/24 

FIELD: industrial chemistry.

SUBSTANCE: invention refers to cooligophenolformaldehyde phthalide-containing novolacs based on 3-phenyl-3-(4'-hydroxyphenyl)phthalide and phenol, the way of their production and to cross-linked phthalide-containing copolymers based on them. The cooligophenolformaldehyde phthalide-containing novolacs are manufactured on the basis of 3-phenyl-3-(4'-hydroxyphenyl)phthalide and phenol with the general formula where m=5-10, p=1-2 as cooligomers for production of cross-linked phthalide-containing copolymers.

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