These solutions are processed at temperatures above 170°C and are used to produce shaped objects, such as films or fibers, or coatings. In addition they are used to determine the molecular weight of polyarylene sulfides or to purify polyarylene sulfides, or to clean apparatuses which were used in the production or pro- cessing of polyarylene sulfides.
