1. Introduction Biodegradable polymers are widely applied in tissue engineering [1,2,3,4,5]. These materials provide easy processing, modification and device fabrication, diversity of chemical and physical properties, and biocompatibility. However, their variability is accompanied by a high specificity of obtained polymer compounds. Even when considering compositions from a single monomer, the difference in their structural, chemical, and biological features can be vast [6,7,8,9].
