Separation of trans‐1,4, cis‐1,4 and 1,2‐vinyl polybutadienes by thin layer chromatography

A study on thin layer chromatographic (TLC) separation of polybutadienes with three different microstructures, namely, trans‐1,4, cis‐1,4, and 1,2‐vinyl, was carried out. An experimental procedure to separate three possible binary mixtures of these polymers into each component species is established in an alternate use of carbon tetrachloride and amyl chloride as developer. Further it is shown that this procedure combined with a two‐dimensional TLC development technique allows to separate the ternary polymer mixture into components. In addition, the chromatographic behavior of so‐called “equibinary” polybutadienes has been investigated using the technique established so far.
