摘　　要：介绍了合成橡胶装置HIPS改性用低门尼F-250的生产技术及在HIPS中的应用情况,对低门尼F-250与正常门尼F-250以及国内外同类产品的性能进行了比较。实际应用表明:降低分子量和凝胶含量后,采用抗氧剂B,门尼粘度控制在40±10的低门尼F-250对HIPS改性具有优良的性能。但降低门尼粘度和分子量,偶合率不变,F-250拉伸强度降低,在轮胎中的应用性能有所影响。In this paper, the industrial development and application of F-250 with lower Mooney viscosity at the synthetic rubber plant, which was employed to modify HIPS, has been introduced. The comparisons about performance among F-250 with lower Mooney viscosity, F-250 with normal Mooney viscosity and other ones have been made. The practical applications have been shown：HIPS modified by F-250 whose performance was better when molecular weight was lower and gel components was lower, after F-250 whose Mooney viscosity is range from 30 to 50 and adequate amounts of antioxidants-B have been added. However, F-250 with lower Mooney viscosity can been used in tires manufactures but with negative effects on performance, though Mooney viscosity, molecular weight, remaining coupling rates unchangeable and its extension capacities were decreased.
