摘　　要：凝胶渗透色谱法(GPC)是测定聚合物相对分子质量及其分布的最常用、有效和快速的一种分析方法。用GPC法测定了含氟聚合物的重均相对分子质量及其分布,以已知相对分子质量的聚苯乙烯为标准样品,绘制了重均相对分子质量的对数与保留时间的标准曲线。测试结果可靠且操作简单,为改进生产工艺条件提供了可靠的科学参考依据。Gel permeation chromatography（ GPC） is one of the most commonly used and effective and quick technique in determination of relative molecular weight and its distribution of polymers. In the paper,the molecular weight and molecular weight distribution of fluoropolymer were determined by gel permeation chromatography（ GPC）,with polystyrene as the standard sample,the standard curve was established by the relationship between logarithmic of molecular weight and retention time. The result is reliable and it＇s simple to operate,it provides reliable scientific references for the improvement of technological conditions in the production.
