*3.2. Polymer Preparation*

#### 3.2.1. PGS Synthesis

Glycerol (0.116 mol, 10.69 g) and sebacic acid (0.145 mol, 29.36 g) were placed in a 250 mL three-necked round bottom flask and placed under nitrogen flow. The reaction was carried out in a closed oven at 170 ◦C for 6 h, providing mechanical stirring (40 rpm) and then the polymer was left cooling overnight under nitrogen flow.
