METHOD OF ALL-PURPOSE MODIFYING AGENT PRODUCTION APPLIED FOR POLYURETHANES AND FOAMED POLYURETHANES Russian patent published in 2008 - IPC C08G18/77 C08K13/02 

FIELD: inorganic chemistry.

SUBSTANCE: invention refers to polymer chemistry particularly to polyurethanes and foamed polyurethanes processing technologies. Described method of all-purpose metal-complex modifier for polyurethane implies solution of metal halogenide in solvent. This method is characterized by solution of metal halogenide having variable valence of stable oxidation level, for example manganese chloride (II) tetrahydrate, in N,N-dimethylethanolamine and ε-caprolactam at mole ratio of metal halogenide: dimethylethanolamine: ε-caprolactam 1:5:5-20. Modifying agent is added to laprole component. Polyurethanes produced with modifying agent are characterized by improved physical-mechanical properties such as ultimate breaking stress, rigidity at deformation 40% and comfort coefficient.

EFFECT: production of polyurethanes with improved physical-mechanical properties; increased comfort coefficient rigidity and ultimate breaking stress.
