Toughening Effect of a China – Made Polyaryletherketone on Polyphenylene Sulfide

The present investigation deals with an attempt to improve the toughness of polyphenylene sulfide (PPS) through blending with a China - made polyaryletherketone (PEK - C). It is found that on certain processing conditions PPS can be made very tough in the case of lower PEK - C content. On the basis of mechanical performance measurement and fractographic analysis, the toughening mechanism is discussed tentatively.
