14 Claims

1. A polyarylene sulfide resin composition, comprising:

100 parts by weight of a crosslinked polyarylene sulfide having a melt index of 50 to 480 g/10 min;

60 to 120 parts by weight of glass fiber; and

0.1 to 0.3 parts by weight of an anti-hydrolysis agent,

wherein the melt index is measured at 315° C. under a load of 5 kg,

wherein the crosslinked polyarylene sulfide has a polydispersity index (PDI) of 5.4 to 6.4,

wherein the crosslinked polyarylene sulfide contains one or more selected from the group consisting of 2,6-diisopropylphenyl isocyanate, 2,6-diisopropylaniline, 1,4-bis(phenylthio)-benzene, 1,6-hexanediol and p-chloro-N-methylanilin in an amount of 100 ppm or less, and

wherein the polyarylene sulfide resin composition has a volatile weight loss of 0.15% or less at 260° C. for 2 hours.
