摘要
Abstract
With special IR5-MCT detector and GPC type rapid column,the new gel chromatography GPC-IR was used to get the molecular weight and its distribution of ultra high molecular weight polyethylene. The molecular weight and its distribution of three kinds of ultra high molecular weight polyethylene were characterized. The experimental results show that the new type of gel chromatography can be used for quantitative determination of extremely dilute the sample solution. The results have a high accuracy,good repeatability and fully meet the requirements of quantitative analysis. The new GPC-IR overcome the traditional high temperature GPC shortcoming that can not analyze the problem of ultra high molecular weight polyethylene.关键词
