ABSTRACT:
Crystalline polymers are readily dissolved in chlorinated diphenyl ether solvents. These solvents and in particular the isomers of chlorodiphenyl ether are especially suitable as solvents for polyarylene sulfides. These solvents are biodegradable and can be conveniently used as alternatives to polychlorobiphenyl solvents.
