POLYARYLENE SULFIDE, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a polyarylene sulfide capable of showing and maintaining excellent properties, and a preparation method thereof, wherein the polyarylene sulfide shows the shape of a pellet having a size of 2-10 mm just after melt polymerization and has a remaining solvent content of 300 ppm or less on the basis of the weight of total resins. Such polyarylene sulfide can show and maintain excellent properties, particularly, in that it does not generate bubbles within a product or strains on a surface, has excellent mechanical properties such as tensile strength and the like, and thus can be helpfully applied to the industrial field with respect to preparation of a polyarylene sulfide and manufacturing of a molded product using the same.
