Abstract
A polyarylene sulfide resin composition that including a polyarylene sulfide having a carboxyl group content of not less than 60 μmol/g; and a glass fiber. Provided is a polyarylene sulfide resin composition that has excellent mechanical strength, particularly weld strength, generates less burrs, and has excellent adhesiveness to an epoxy resin. Also disclosed are articles made from such compositions as well as methods of making the compositions and article made therefrom.

-9. (canceled)
A polyarylene sulfide resin composition comprising:
- 100 parts by weight of (A) a polyarylene sulfide having a carboxyl group content of not less than 60 μmol/g;
- and
- 10 to 400 parts by weight of (B) a glass fiber,
- wherein, when the cumulative integral value from the molecular weight of 100 to the molecular weight of 10,000 in a molecular weight distribution curve of (A) the polyarylene sulfide is taken as 100, the cumulative integrated value at the molecular weight of 4,000 is 48 to 53, and
- wherein, when the melt flow rate of (A) the polyarylene sulfide is defined as MFR1, and when the melt flow rate obtained after mixing (A) the polyarylene sulfide with an epoxy silane coupling agent at a weight ratio of 100:1, and heating the resulting mixture at 315.5° C. for 5 minutes is defined as MFR2, the rate of change represented by MFR2/MFR1 is not more than 0.085.
