Abstract
A method for coating arylene sulfide polymers onto substrates by applying to the surface of the substrate a sufficient amount of a compound that acts as an aid in obtaining a smooth surface of arylene sulfide polymer over the substrate, applying a sufficient amount of arylene sulfide polymer to form a surface coating, and raising the temperature of the coated surface sufficiently to cure the coating of arylene sulfide polymer. In one embodiment, the compound acting as an aid in obtaining a smooth surface is applied as a film over the substrate surface and this film is overcoated with poly(arylene sulfide). In another embodiment, the aid for obtaining a smooth surface is applied over the substrate as part of a powdered mixture containing both the compound and powdered poly(arylene sulfide).
