Conclusions
An optical method of determining the ability of liquids to precipitate polymers in selecting a precipitation bath composition has been proposed.
A special feature of this method is the low duration of the determination, the low consumption of chemicals, and the possibility of analyzing spinning solutions without preliminary dilution.
