Cellulosic molding and spinning compound with low contents of low-molecular decomposition products

Molding or spinning substance, comprising by weight 4.99-25% cellulose, 95-50% of a tertiary amine oxide, in given instances up to 25% of a non-solvent and up to 10% of other polymers, all proportions relative to the weight of the molding or spinning substance, and as additive, singly or in a mixture, 0.01 up to 0.5% by weight, relative to the tertiary amine oxide, of an organic compound with a minimum of four carbon atoms and a minimum of two conjugated double bonds and a minimum of two groups in the form of hydroxyl and/or amino groups which, in turn, have a minimum of one unsubstituted hydrogen atom and/or contain glycerol aldehyde, said additive being soluble in said tertiary amine oxide as well as its mixture with said non-solvent.
