Method of manufacturing articles from materials containing cellulose

object of the invention is a method for the production of compact cellulose-containing moldings Reacting optionally modified organic polyisocyanates with cellulose, in particular lignocellulose, in the presence of mold release agents in an open or closed mold, which is characterized is characterized in that as mold release agents aminopropyl used-containing siloxane compounds of general formula (I) will, which meanR1 CH3 and / or R2.R2 -CH2)xNH-R3 and or -(O)y- (CH2)xNH-R3 '.R3, R3 ' independently H or -CH2)xNH2 could be,R4 -CH2)x-NH- (CH2-CH2-O)z-R5 WithR5 aryl or alkyl,n 50 to 1000,m is 0 to 20, with the ratio m : N = 0 to 0.4,k is 0 to 20,x 1 to 20,y is 0 or 1,z 1 to 20,with the proviso that at least one amino-functionalized radical is present.
