Abstract
Official abstract text for this publication.
The resin composition comprises (A) 100 parts by weight of a polyarylene sulfide resin (component A) synthesized through a polymerization reaction using an aromatic disulfide-based compound as a polymerization terminator and (B) 10 to 180 parts by weight of carbon fibers (component B), wholly aromatic polyamide fibers (component C) or glass fibers (component D).
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin composition produced by melt kneading components comprising: (A) 100 parts by weight of a polyarylene sulfide resin (component A) synthesized through a polymerization reaction using an aromatic disulfide-based compound as a polymerization terminator, and (C) 10 to 150 parts by weight of a fiber (component C), wherein the component C is at least one selected from the group consisting of a para-aramid fiber and a meta-aramid fiber, based on 100 parts by weight of the component A, wherein the component C has a fiber length of 0.1 to 3 mm, and wherein the component C is sized with at least one sizing agent selected from the group consisting of a polyester, a polyurethane and a polyether sulfone resin. 2. The resin composition according to claim 1 , wherein the aromatic disulfide-based compound is at least one selected from the group consisting of a benzothiazole and a diphenyl disulfide. 3. A molded article comprising the resin composition of claim 2 . 4. The resin composition according to claim 1 , wherein the aromatic disulfide-based compound is at least one selected from the group consisting of diphenyl disulfide and dithiobisbenzothiazole. 5. A molded article comprising the resin composition of claim 4 . 6. The resin composition according to claim 1 , wherein the component A is a polyarylene sulfide resin obtained by directly heating and polymerizing a diiodoaryl compound, solid sulfur and an aromatic disulfide-based compound without using a polar solvent. 7. A molded article comprising the resin composition of claim 6 . 8. A molded article comprising the resin composition of claim 1 . 9. The resin composition according to claim 1 , wherein the composition has a dynamic friction coefficient of not more than 0.47. 10. The resin composition according to claim 1 , wherein the composition has an impact strength of 12 KJ/m 2 or more.
