Polyarylene sulfide solutions, process for the preparation thereof and use thereof

摘要

Solutions are described containing polyarylene sulfide and, as solvent, quinoline and/or isoquinoline and/or substituted derivatives thereof, the solvent being liquid at 25 DEG C. These solutions are processed at temperatures above 170 DEG 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 processing of polyarylene sulfides.
