Chromatography aliphatic polyesters

The versatility of the 2D approach is illustrated with a four-arm starshaped block copolymer (a mixture of 16 components), which was synthesized in our laboratories to understand and demonstrate the advantages of 2D chromatography. These 16 components are a mixture of four different styrene-butadiene (St-Bd) copolymer compositions, each consisting of four molar masses (the St-Bd precursor with one to four arms). Another polymer investigated is a real-world application the deformulation of a telomeric aliphatic polyester.
