METHOD OF OBTAINING MODIFIER FOR THERMOREACTIVE SYNTHETIC RESINS Russian patent published in 2008 - IPC C08B31/18 C08G16/04 

FIELD: chemistry.

SUBSTANCE: invention pertains to the method of obtaining modification products of phytogenous starch-containing raw materials, used for modifying formaldehyde-containing thermoreactive resins, widely used in industry. Description is given of the method of obtaining the modifier for synthetic thermoreactive formaldehyde-containing resins by oxidative modification of the starch-containing raw material in a water alkaline suspension, under aeration conditions of the reaction mixture, in the presence of a catalyst - metal ion and chemically active components, relative to the starch-containing material, chosen from a group which includes melamine, dicyandiamide, carbamide, toluenesulphamide, caprolactam, phenol, resorcin or their mixture, at 50-100°C until obtaining a free-flowing reaction mixture with viscosity of 20-60 cP measured using viscometer "ВЗ-6".

EFFECT: method allows obtaining low-toxic wooden slabby materials, with high water resistance and strength.
