Biodegradable polymers have gained a lot of interest in recent decades. Their ability to biodegrade under natural environmental conditions, combined with their biological safety, has led to their increasing use in various areas of our lives, such as the packaging industry, agriculture, geotextiles, pharmaceuticals or medicine . A growing field of application for such polymers is biomaterial applications which are directly related to the regeneration or 'repair' of human tissues. The term of 'biomaterials' is used to describe, for example, drug carriers, tissue scaffolds or other biomedical devices such as sutures, pins, meshes or tissue-stabilising elements . Among the biodegradable polymers, aliphatic polyesters, such as polylactide (PLA), poly(lactide-co-glycolide) (PLGA) or polycaprolactone (PCL), are a prominent group, characterised by good mechanical parameters, consistent properties and biocompatibility . In recent years, the popularity of another representative of this group -poly(butylene succinate) (PBS)has increased. This popularity is related to its excellent biocompatibility, reasonably balanced thermo-mechanical properties and very good thermoprocessability .
