ACCELERATOR SOLUTION AND METHOD OF CURING CURABLE RESINS Russian patent published in 2016 - IPC C08K5/00 C08L67/06 

FIELD: chemistry.

SUBSTANCE: accelerator solution contains (i) at least one organic solvent, (ii) a manganese salt, a copper salt or a combination thereof, and (iii) a complex of iron with a nitrogen donor ligand having a structure of the formula , where R is hydrogen, F, Cl, Br, hydroxyl, C_1-4-alkyl-O-, -NH-CO-H, -NH-CO-C_1-12-alkyl, -NH₂, NH-C_1-12-alkyl and C_1-12-alkyl; R1 and R2 are C_1-24-alkyl, C_6-10-aryl and a group containing a heteroatom, capable of coordinating at a transition metal; R3 and R4 are hydrogen, C_1-12-alkyl, C_1-12-alkyl-O-C_1-12-alkyl, C_1-12-alkyl-O-C_6-10-aryl, C_6-10-aryl, C_1-12-hydroxyalkyl and (CH₂)_nC(O)OR5, R5 is hydrogen and C_1-4-alkyl, and n varies from 0 to 4, X is C=O, -[C(R6)₂]_y-, where y varies from 0 to 3, and each R6 is hydrogen, hydroxyl, C_1-12-alkoxy and C_1-12-alkyl.

EFFECT: invention enables to obtain a nontoxic accelerator, having high reactivity and high curing efficiency of the curable resin.
