Zusammenfassung:	FIELD: chemical technology, more particularly, manufacture of plastic materials to prepare composite materials with minerals and organic fillers. SUBSTANCE: method comprises treating wood with acetic anhydride on heating in the presence of magnesium perchloriate catalyst. Wood is treated with mixture of acetic anhydride with monobasic saturated carboxylic acid having from 2 to 8 carbon atoms used in equimolar ratio of 8-10 moles respectively per 3- 10 moles at 100-130 C for 4-6 h, amount of magnesium perchlorate being used in amount of 20% based on weight of wood. EFFECT: desired product is readily soluble in organic solvents and is highly substitutable. 32 ex, 6 tbl
