Abstract

Abstract A one-pot synthesis of stereomer cross-linked copolymers of l-malic acid with tuned properties is reported. The β-cyclodextrin, as co-monomer with several OH groups, was applied to promote the polyester formation with higher, pre-defined molecular weight. The importance of the experimental conditions for preparation of polymers with tailor-made, optically active compositions is described, and their structures are characterized by different techniques such as thermogravimetry-differential scanning calorimetry-mass spectrometric evolved gas analysis, infrared spectroscopy and specific rotation. To our knowledge, first time was used the specific optical rotation for characterization of retention of the optical activity in the course of the synthesis.
