Predetermined amounts of ε-caprolactone (ε-CL, Alfa Aesar, USA; 500 mmol), L-lactide (LA, Medichem, South Korea; 500 mmol), stannous octoate (Sn(Oct)2, Alfa Aesar, USA; 5 mmol), and 1-dodecanol (Alfa Aesar, USA; 0.2, 0.1, and 0.05 mmol for molecular weights of 60k, 140k, and 200k, respectively) were added into a dried glass ampule equipped with a magnetic stirring bar. The ampule was sealed under vacuum after purging three times with N2 at 90 °C and heated in an oil bath at 150 °C. After the reaction for 24 h, the product was dissolved in chloroform and microfiltered through a membrane filter with a pore size of 0.45 μm. It was then precipitated by pouring the polymer solution into excess methanol to remove the catalyst and unreacted monomers, filtered, and dried in a vacuum oven at 50 °C for 24 h. The products were analyzed by 1H nuclear magnetic resonance (NMR) and gel permeation chromatography (GPC) (Supplementary Fig. S1 ).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
