摘　　要：针对聚丙烯T38F产品在加工过程中出现的质量波动问题,分析了不同批次T38F的相对分子质量及其分布、流变性能和挤出加工性能。结果表明,产品相对分子质量及其分布波动较大是造成加工性能不稳定的内在原因。经过调整催化剂体系、抗氧剂体系及相关工艺条件,使T38F产品质量稳定,达到指标要求。This paper analyzed the relative molecular mass and its distribution, rheological property and extrusion processability of different batches of polypropylene （PP） resin, grade T38F, aiming at eliminating its fluctuation in quality happened during the processing course. The results confirmed that it was the variation in relative molecular mass and its distribution of the resin that caused the instability in processability of grade T38F. After adjusting the catalyst system, antioxidant system and the related technological parameters, the quality of the products made of grade T38F stabilized and came up to the requirements stipulated in the product specification.
