摘　　要：根据医用级低密度聚乙烯(LDPE)树脂性能的要求,确定了LDPE LD26F的质量指标,实现了对产品密度、正己烷溶出物、反应温峰平稳等生产难点的控制,开发了医用级LDPE薄膜树脂LD26F。分析结果表明:LD26F的维卡软化点为103.8℃,拉伸强度为13.01 MPa,弯曲模量为228.0 MPa,LD26F具有良好的耐热性能、优良的力学性能和加工性能;LD26F的正己烷提取物满足国家标准。The quality indicators of LDPE LD26F are determined, according toresuire- ments for the properties of medical grade LDPE film resin. Some production difficulties such as product density, hexane extrat and the stability of reaction temperature ect are controlled successfully, and the film resin LD26F of medical grade LDPE is developed. The analytical results show that Vicar softening point of LD26F is 103. 8℃, tensile strength is 13.01 MPa, flexural modulus is 228.0 MPa, and LD26F has good heat resist- ance. excellent mechanical properties and processing performance; and hexane extracts of LD26F meet the national standard requirements.
