Abstract
The present invention relates to a polyarylene sulfide resin composition having good processability and showing excellent properties due to its more improved miscibility with other polymer materials or fillers, and a formed article. Such polyarylene sulfide resin composition includes a polyarylene sulfide including a disulfide repeating unit in the repeating units of the main chain; and at least one component selected from the group consisting of a thermoplastic resin, a thermoplastic elastomer, and a filler.

A polyarylene sulfide resin composition, including a polyarylene sulfide including a disulfide repeating unit in the repeating units of the main chain and having a target viscosity;
- and at least one component selected from the group consisting of a thermoplastic resin, a thermoplastic elastomer, and a filler,
- wherein the polyarylene sulfide includes carboxyl group (—COOH) bonded to at least part of end groups of the main chain,
- wherein the polyarylene sulfide is prepared by a method comprising the steps of:
- (a) melt-polymerizing a reactant comprising a diiodoaromatic compound and elemental sulfur while adding a polymerization, and (b) adding a compound having a carboxyl group group;
- and
- wherein an FT-IR spectrum of the polyarylene sulfide shows a first peak between 1400 cm and 1600 cm−1 and a second peak between 1600 cm and 1800 cm−1, wherein a height intensity of the second peak is between about 0.1% and about 10% of a height intensity of the first peak.
