USE OF HETEROMETALLIC COMPLEX OF FORMULA Co4Fe2O(L)8'4DMF'H2O, WHEREIN L IS RESIDUE OF A PRODUCT OF CONDENSATION OF SALICYLIC ALDEHYDE AND MONOETHANOLAMINE H2L, AS POLYURETHANE MODIFIER

摘要

The invention relates to use of coordination compounds as polyurethane modifiers, in particular to use of heterometallic complex of formulaCoFeO(L)4DMFHO,wherein L is residue of a product of condensation of salicylic aldehyde and monoethanolamine HL, DMF is dimethylformamide, as polyurethane modifier. Prepared polyurethanes have high indices of mechanical properties.
