摘要

<正> The compositional homogeneity of a poly （ethylene terephthalate）-poly （tetramethylene ether） multiblock copolymer sample with low content of hard segment was examined by GPC

TLC

and solubility method. The copolymer sample was found to have a uniform composition as a function of elution volume over the major portion of sample from GPC method. However within one elution fraction

the copolymer chains

although having the same hydrodynamic volume

may have some difference in composition. Two fractions with different composition were obtained by precipitation in ethanol. Some low molar mass copolymers were also separated by a TLC technique from the copolymer sample.
