Abstract: A new gel permeation chromatographic(GPC) method for the analysis of relative molecular mass and distribution of petroleum resin of C5 hydrogenation using the universal calibration has been established. In the method reference material of small molecule of fit value is seiected.The determated results showed that the method is accurate,reliable and highly repeatable. The characterized chromatograms are straightforward and understandable, which has a very important significance for the study of mechanical properties,fluidity,processability and other properties of C5. This is an effective analytical method for the petroleum resin of C5 hydrogenation.  

Key words: relative molecular mass and distribution; petroleum resin; GPC
