综述了间同立构聚苯乙烯（SPS）合成中均聚烯烃催化剂的研究进展。SPS是一种新型半结晶工程热塑性塑料，结晶熔点为270°C。由于其结晶性质，SPS具有高耐热性、优异的耐化学性和耐水/耐蒸汽性。本文综述了聚合反应和立体定向反应的机理模型，以及影响催化剂活性和立体定向性的因素。
The current development of the metallocene-based catalysts for syndiotactic polystyrene (SPS) has been reviewed. SPS is a new semi crystalline engineering thermoplastic with a crystalline melting point of 270°C. Because of its crystalline nature, SPS has high heat resistance, excellent chemical resistance and water/steam resistance. In this review, some mechanistic models for polymerization and stereoregulation, as well as the factors which affect the activity and stereospecificity of the catalysts, are discussed.
