Abstract
Disclosed are polyarylene sulfide compounds and melt-processed shapes therefrom in the form of extruded profiles, tubings, pipes, fibers, monofilaments and films. Embodiments especially adapted from the invention are elongated spooled tubings exhibiting a smooth surface texture, spoolability and chemical resistance. The compounds contain polyarylene sulfide, a highly saturated, hydrogenated (if applicable) nitrile copolymer; and an organofunctional silane. The compounds exhibit spherical microdomains of the nitrile copolymer in diameters ranging from 0.1 μm-100 μm.
