摘　　要：以脂肪族聚碳酸酯(PPC)为增韧剂对丁腈橡胶/四水硫酸高铈(NBR/Ce(SO_4)_2·4H_2O)复合材料进行了增韧改性,使用差示扫描量热分析(DSC)、热重分析(TGA)、溶胀平衡法、扫描电子显微镜(SEM)、硫化性能测试和力学性能测试等手段表征其结构和性能。结果表明:Ce(SO_4)_2·4H_2O对NBR/PPC/Ce(SO_4)_2·4H_2O复合材料起配位交联、增容和填充补强作用,PPC起促进分散和增韧剂的作用。The acrylonitrile-butadiene rubber/ceric sulfate（NBR/Ce（SO_4）2· 4H_2_O） composites materials were toughened with poly（propy1 ene carbonate）（PPC）. And the structure and properties of NBR/PPC/Ce（SO_4）_2· 4 H_2O composites materials were investigated by differential scanning calorimetry, thermogravimetric analysis, equilibrium swelling method, scanning electron microscopy, curing performance test and mechanical property. The results show that Ce（SO_4）_2· 4 H_2O mainly serves as coordination crosslinking agent, compatibilizer and reinforcing filler, while PPC mainly plays the role of toughening agent.
