Abstract
Provided are a polyarylene sulfide having a chloroform soluble content of at most 0.5% by weight and having an inherent viscosity ηinh of from 0.05 to 0.4; a polyarylene sulfide resin composition comprising a polyarylene sulfide and an inorganic filler, of which the chloroform soluble content is at most 0.5% by weight relative to the polyarylene sulfide in the composition; car parts produced through injection molding of the composition; and a method for producing a polyarylene sulfide. The polyarylene sulfide has a reduced content of low-molecular components, and has well balanced properties of fluidity, flexural strength and impact resistance.
Claims7
A polyarylene sulfide resin composition comprising (A) from 30 to 80% by weight of a polyarylene sulfide and (B) from 20 to 70% by weight of an inorganic filler, of which the chloroform soluble content is at most 0.5% by weight relative to the polyarylene sulfide in the composition.
A polyarylene sulfide resin composition comprising:
- (A) from 30 to 80% by weight of a polyarylene sulfide;
- and
- (B) from 20 to 70% by weight of an inorganic filler,
- wherein said polyarylene sulfide resin is prepared by reacting a dihalogenoaromatic compound with lithium sulfide in an aprotic organic solvent, in the presence of 21 to 100 mol % relative to lithium sulfide, of lithium hydroxide.
