Kind Code:
A1
Abstract:
Disclosed in the present invention is a PPS composition. Two types of linear PPS resins are used, wherein the PPS resin prepared with the sodium sulfide method is obtained by reacting dichlorobenzene with sodium sulfide and has an active group capable of reacting with a GMA toughening agent for grafting, and then a specific amount of linear PPS resin prepared with the sulfur method can improve the fluidity of the PPS composition. Therefore, the PPS composition provided by the present invention has high toughness and good fluidity at the same time.
