摘　　要：将苯乙烯／ 丙烯酰胺共聚物（ＰＳＡｍ） 负载到ＳｉＯ２ 上，制得ＰＳＡｍ／ＳｉＯ２ 复合载体，用Ｘ射线光电子能谱，扫描电镜，热失重，红外光谱分析等对其进行了表征． 并对ＰＳＡｍ／ＳｉＯ２ 负载的茂金属催化剂进行了乙烯聚合的研究，证明该催化剂活性较高，并可有效的控制所得聚乙烯的颗粒形态．The organic/inorganic complex support was prepared by impregnating SiO 2 with poly(styrene co acrylamide)(PSAm) and metallocene was then supported on it. The support and ca talyst obtained have been examined by XPS, SEM, TGA and IR and its catalytic activity for ethylene polymerization has been studied.
