Abstract

Samples of allumochromphosphate modifiers are synthesized based on the acid                   orthophosphates of aluminum and chrome of different oxidation degree. Their effect on viability of carbamide- formaldehyde resins and physical-mechanical properties of wood particle boards is studied. The possibility of reducing the formaldehyde emission from wood particle boards is shown when such modifiers are used.
