摘　　要：合成了聚苯乙烯负载的茂金属催化剂,考察了硅胶用量、二乙烯基苯与苯乙烯体积比、洗涤温度和洗涤次数对催化剂的影响,并对其进行了表征。确定硅胶加入量为1g,二乙烯基苯与苯乙烯体积比为0.08,洗涤温度60℃,洗涤次数为4次;XPS表征证明合成了聚苯乙烯载体茂金属催化剂。This paper synthesized the metallocene catalyst supported polystyrene carrier, and studied the effect of content of silica, the volume ratio between 2-vinyl-benzene and styrene, washing temperature and washing times on the catalyst which was also characterized. Decided the addition of silica 1 g, the volume ratio between 2-vinyl-benzene and styrene was 0.08, washing temperature was 60 ℃, and washing times was four times, The XPS characterization proved metallocene catalyst supported polystyrene carrier was successfully synthesized.
