Aliphatic polyesters are great materials for biomedical applications such as sutures, temporary implants or other devices because they are biocompatible and biodegradable. As long as they are synthesized by ring opening polymerization or melt polycondensation, using metallic or organometallic catalyst, the final polymer is contaminated by potentially toxic metallic residues that are difficult to remove. One environmentally friendly alternative to overcome this problem is the use of enzymes in the polymerization [1, 2]. In this work we have synthesized a series of random aliphatic copolyesters made of epsilon- caprolactone and butylene succinate (Figure 1) by enzymatic polymerization and characterized their chemical structure and thermal behaviour.
