Parent homopolymers are baseline separated from the block copolymers with nonpolar arms in a single step with the help of liquid chromatography under limiting conditions of enthalpic interactions. The small differences in the chain solubility are employed to apparently originate two similar but independent liquid chromatography retention mechanisms, enthalpic partition (absorption) and phase separation (precipitation). For the first time, the option is demonstrated to separate a complex polymer system with a tandem of two independent liquid chromatography procedures.
