Abstract
Knowledge of the exact composition and purity of advanced copolymers is of utmost importance given their influence on the final physical properties. The development of analytical techniques to examine these impurities is therefore crucial with respect of large industrial productions. A comprehensive two-dimensional HPLC separation technique with a slow size exclusion (SEC) separation in the first dimension and a fast reversed phase liquid chromatography (RPLC) separation in the second dimension was therefore developed. For the SEC dimension, two 2 mm internal diameter columns were packed with a PLgel Mixed-D packing and in the RPLC dimension a Kinetex (C18) column packed with solid core/porous shell particles were applied. The optimized setup allowed for successful qualitative and semi-quantitative analysis of various types of in-house prepared copolymers, including block, graft and palm-tree types of structures.
