Conclusions
The immersion liquids for determining the refractive indices of polymeric materials have a number of advantages over the known ones.
It is possible to determine the refractive indices of man-made fibers by the chromatic variation method using 20 immersion liquids in the range of values 1.71–1.48, with an accuracy of 0.002.
A method has been proposed for determining the refractive indices, dispersions, and birefringence of man-made fibers of cylindrical form using a single immersion liquid.
