PHTHALIDE-CONTAINING COOLIGOMERS FOR PRODUCING CROSS-LINKED PHTHALIDE-CONTAINING COPOLYMERS, PRODUCTION METHOD THEREOF (VERSIONS), PHTHALIDE-CONTAINING CROSS-LINKED COPOLYMERS BASED THEREON AS ENGINEERING POLYMERS Russian patent published in 2012 - IPC C08G8/24 C08G8/28

Abstract RU 2463315 C1

FIELD: chemistry.

SUBSTANCE: phthalide-containing cooligomers are cooligomers based on phthalide-containing phenols, isomeric cresols and phenol of general formula: (I) R₁=CH₃; CH₂OH; R₂=H; OH; R₃=H; CH₂OH; m=1-5, p=1-5, k=1-2 for producing cross-linked phthalide-containing copolymers.

EFFECT: obtaining novel resol-type phthalide-containing cooligomers with high rate of hardening, providing methods of producing said cooligomers which are then used to obtain novel cross-linked phthalide-containing copolymers, which have potential for use in producing heat-resistant and electroactive structural polymer materials.
