PHTHALIDE-CONTAINING COOLIGOMERS FOR PRODUCING CROSS-LINKED PHTHALIDE-CONTAINING COPOLYMERS, PRODUCTION METHOD THEREOF (VERSIONS), PHTHALIDE-CONTAINING CROSS-LINKED COPOLYMERS BASED THEREON AS ENGINEERING POLYMERS

摘要

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. ^ 5 cl, 20 ex, 4 tbl
