Abstract

Spinning solutions are obtained by dissolving polyacrylonitrile or a copolymer of acrylonitrile, e.g. with acrylamide, in a mixture of dimethyl formamide and one or more acetals, for example those obtained by reacting an aldehyde such as formaldehyde, acetaldehyde or benzaldehyde and an alcohol such as methyl, ethyl, propyl or n-butyl alcohol, or glycol, the acetal preferably being added in an amount of 5-15 per cent of the dimethyl formamide.
