preparation	The PPS Resin was dried under vacuum at 120 °c for 12 h, and then in accordance with 0. 5%, 1. 0%, 3. 0% and 5. 0 %(mass fraction, the same below) mixing ratio of the antioxidant GA 80 and PPS Resin are mixed evenly, and then the micro twin-screw extruder is used for melt blending and extrusion, the partition temperature of the screw extruder was 280, 285, 290 ℃, the blending time was 3 min, and the screw speed was 25 r/min, where x is the content of the antioxidant GA Δ80.
effect	The antioxidant GA Δ80 has good compatibility with PPS, and can be uniformly dispersed in the PPS matrix, when the content of GA +80 is more than or equal to 3. 0%, GA 80 will produce partial agglomeration.
