MOLECULAR WEIGHT DETERMINATION OF CARBOPHENOXY TERMINATED AROMATIC POLYESTERS BY THIN LAYER CHROMATOGRAPHY
薄层色谱法测定端羰苯氧基聚芳酯的分子量

The thin layer ehromatography (absorbent: Silica-gel; developer: chloroform-benzene=2:1) has been applied to the determination of molecular weight of carbopbenoxy terminated aromatic polyesters. It is as accurate as spectrophotometry.
