Title:
POLYARYLENE SULFIDE HAVING EXCELLENT FORMABILITY, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2011/142557
Kind Code:
A2
Abstract:
The present invention relates to a polyarylene sulfide in which a ratio of a peak area of a polymer chain of a second polyarylene sulfide, having a molecular weight equal to or lower than the maximum peak molecular weight, to a peak area of a polymer chain of a first polyarylene sulfide, having a molecular weight equal to or higher than the maximum peak molecular weight, is 1.3 or less in the molecular weight distribution of the polyarylene sulfide as measured by gel permeation chromatography using polystyrene as a standard. The present invention also relates to a method for preparing the polyarylene sulfide. The polyarylene sulfide of the present invention has excellent formability, generates no burrs or the like, and can be well-formed into products which require high molding accuracy.
