POLYPHENYLENE SULFIDE COMPOSITION

摘要

PURPOSE:To provide the subject composition freed from such drawbacks for the films therefrom as low yield and low planarity resulting from being subject to breakage of biaxially oriented polyphenylene sulfide films produced by conventional method in film forming process such as biaxial orientation or heat setting. CONSTITUTION:The objective composition characterized by (1) p-phenylene sulfide unit accounts for >=90mol% of the total recurring units; (2) the amount extractable with acetone accounts for <=0.5wt.% of the final composition; and (3) count of residual unmelted nuclei is <=10 counts/g.
