Method of manufacturing articles from materials containing cellulose

Method for preparing compact, cellulosic-containing shaped articles (A) by reaction of organic polyisocyanates (I), optionally modified, with cellulosic (II), particularly lignocellulose, in presence of a mold-release agent (X) in an open or closed molding tool. The new feature is that (X) is a silo...

Zusammenfassung:	Method for preparing compact, cellulosic-containing shaped articles (A) by reaction of organic polyisocyanates (I), optionally modified, with cellulosic (II), particularly lignocellulose, in presence of a mold-release agent (X) in an open or closed molding tool. The new feature is that (X) is a siloxane compound containing aminopropyl groups. Method for preparing compact, cellulosic containing shaped articles (A) by reaction of organic polyisocyanates (I), optionally modified, with cellulose (II), particularly lignocellulose, in presence of a mold-release agent (X) in an open or closed molding tool.
