英文摘要：

Polyphenylene sulfide （PPS） is a high-performance engineering plastics with high temperature re- sistance, corrosion resistance, radiation resistance, abrasion resistance, favorable electrical properties, di- mensional stability and flame resistance, thus it is widely used in electrical and electronic, petrochemical processing, automotive, environmental protection and other fields. The merits and drawbacks of PPS chemi- cal modification are described briefly, and the filling and blending physical modification are systematically elaborated. The filling includes inorganic fillers and fibers, and the blending includes common plastics, en- gineering plastics and super engineering plastics. Ultimately, the commendations for industrial development of PPS modification are put forward.
