FIELD: metallurgy.
SUBSTANCE: invention concerns receiving technology of para-aramide fibers, films, paper. Particularly it concerns receiving of polymer solutions for its manufacturing. Nonfibrous polymer solutions contains from 1 till 8 % wt of para-aramide at least, 50 % mol. aromatic remains of which are unreplaced; polar amide solvent, chosen from N- methyl -2- pyrrolidone, N,N'- dimethyl formamide, N,N'- dimethyl acetamide, tetra methyl urea and its mixtures; from 0.5% wt of chloride of alkaline or alkali-earth metal and till 7.5 % wt chloride of alkaline or alkali-earth metal, and till 5% wt of water. At least 50 % wt of formed hydrochloric acid is neutralised with receiving of solution, allowing dynamic viscosity, which is at least three times less than dynamic viscosity of polymer solution without neutralisation.
EFFECT: receiving of nonfibrous polymer solution and para-aramide resembling pulp fiber, paper and film, manufactured from specified polymer solution.
