        摘要：Syndiotactic polystyrene (sPS) is a newly crystal engineer plastics. Compared with atactic polystyrene ,it has perfect properties,such as high thermal resistance temperature,high crystallization velocity and chemical resistance. So the research on sPS has carried out recently. In this paper,almost all kinds of sPS alloys for recent ten years were concluded,including sPS/elastomer alloys,sPS/polyester alloys and sPS/nylon alloys. The mechanical and heat resistance properties were also introduced in detail and the compatible agents were introduced.
