摘要：
The determination of the average weight (Mp) and numerical (Mn) of molecular masses of certain indigenous polyethylenglycols by direct and inverse gas chromatography is presented. 2,6 diphenylphenylene oxide (direct chromatography) and polyethylenglycols (inverse chromatography) were used as Tenax stationary phases. The values for the average numerical molecular masses by direct and inverse gas chromatography are comparable.
