Abstract
The present invention relates to the use of a linear synthetic polymer having a molecular weight of from 5.sup.. 10.sup.3 to 1.sup.. 10.sup.7 to improve the strength, to reduce the fibrillation tendancy and to regulate the water absorption properties of a cellulose shaped body, derived from a dissolution of cellulose in a tertiary amine oxide. The linear synthetic polymer may be a polyalkylene, a polyalkylene glycol or a polyacrylate or polymetacrylate or its copolymers with other monomers.
