Abstract

A polyarylene sulfide resin composition which is excellent in mechanical strength as well as electromagnetic shielding effect, slidability and moist heat resistance.
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

1 . A resin composition 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 (B) 10 to 180 parts by weight of carbon fibers (component B), wholly aromatic polyamide fibers (component C) or glass fibers (component D).

2 . The resin composition according to claim 1 , wherein the aromatic disulfide-based compound is at least one selected from the group consisting of benzothiazoles and diphenyl disulfides.

3 . 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.

4 . 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.

5 . The resin composition according to claim 1 , comprising 15 to 180 parts by weight of the carbon fibers (component B) based on 100 parts by weight of the component A.

6 . The resin composition according to claim 1 , comprising 10 to 150 parts by weight of the wholly aromatic polyamide fibers (component C) based on 100 parts by weight of the component A.

7 . The resin composition according to claim 1 , wherein the component C is at least one selected from the group consisting of para-aramid fibers and meta-aramid fibers.

8 . The resin composition according to claim 1 , wherein the component C is wholly aromatic polyamide fibers sized with at least one sizing agent selected from the group consisting of polyesters, polyurethanes and polyether sulfone resin.

9 . The resin composition according to claim 1 , comprising 18 to 150 parts by weight of the glass fibers (component D) based on 100 parts by weight of the component A.

10 . A molded article comprising the resin composition of claim 1 .

11 . A molded article comprising the resin composition of claim 2 .

12 . A molded article comprising the resin composition of claim 3 .

13 . A molded article comprising the resin composition of claim 4 .

14 . A molded article comprising the resin composition of claim 5 .

15 . A molded article comprising the resin composition of claim 6 .

16 . A molded article comprising the resin composition of claim 7 .

17 . A molded article comprising the resin composition of claim 8 .

18 . A molded article comprising the resin composition of claim 9 .
