Zusammenfassung:	PCT No. PCT/SE95/00925 Sec. 371 Date Feb. 13, 1997 Sec. 102(e) Date Feb. 13, 1997 PCT Filed Aug. 15, 1995 PCT Pub. No. WO96/05953 PCT Pub. Date Feb. 29, 1996A granulate of wood or some other cellulose-containing material, pieces or particles of said material being at least partially esterified with 10-50% of a dicarboxylic acid anhydride and then impregnated with 2-25% of a polyol, the granulate being stable in storage and being possible to hot press or hot form later. A method for preparing the granulate by esterification at 80-160 DEG C. and, subsequently, impregnation at 150 DEG C. at most. A method for manufacturing formed articles by hot pressing or hot forming of the granulate, without the presence of a formaldehyde-containing adhesive and preferably without the presence of any other type of adhesive.
