Conclusions
A method for the quantitative determination of low-molecular fraction content in spinning solutions of poly-meta-phenyleneisophthalamide in dimethylacetamide has been established and developed using UV-spectroscopy; this is a basic procedure.
The effect of the composition of the reaction mixture on the LMF content of the spinning solution has been shown.
