## Abstract **Summary:** The microwave (MW)‐assisted lipase‐catalyzed ring‐opening polymerization of __ε__‐caprolactone in boiling solvents was investigated for the first time. In case of boiling toluene or benzene the MW‐assisted reaction proceeded significantly slower compared to oil bath heating
## Abstract The biomedical applications of poly(ε‐caprolactone) (PCL) were limited for its high hydrophobicity and crystallinity. In this study, we copolymerized CL with amorphous 5‐hydroxyl‐trimethylene carbonate (HTMC) to solve the problem. The 5‐benzyloxy‐trimethylene carbonate (BTMC) was synthe
## Abstract A new lipase from the yeast __Yarrowia lipolytica__ was isolated and used in the enzymatic ring‐opening polymerization of lactones. The effect of used commercial oil from a vacuum pump (instead of olive oil) and in the presence of wheat flour was evaluated. It was found that lipase prod
