METHOD FOR PRODUCING MOLDED BODIES MADE OF MATERIALS CONTAINING CELLULOSE

The invention relates to a method for producing compact molded bodies that contain cellulose by reacting optionally modified organic polyisocyanates with a material that contain cellulose, in particular a material that contains lignocellulose, in the presence of mold release agents in an open or clo...

Beschreibung
Zusammenfassung:	The invention relates to a method for producing compact molded bodies that contain cellulose by reacting optionally modified organic polyisocyanates with a material that contain cellulose, in particular a material that contains lignocellulose, in the presence of mold release agents in an open or closed molding tool. The method is characterized in that a mold release agent is used that contains special functionalized siloxane compounds that have alkyl or alkoxy groups and at least one phosphate or phosphoric acid ester. The invention also relates to corresponding mold release agents and to the molded bodies that can be obtained using the method according to the invention.
