FIELD: textiles, paper.
SUBSTANCE: according to the method the polymer is mixed with a solvent, stirred, melted, homogenised and degassed, and then unloaded. Liquid sulfuric acid is used as a solvent, and at least stirring, homogenising and degassing is carried out in a single or twin screw kneading reactor, preferably of continuous operation.
EFFECT: invention enables to simplify and reduce the cost of the method of obtaining the spinning solution.
