## Abstract The ring‐opening polymerization (ROP) of __ε__‐caprolactone (__ε__‐CL) using lanthanide thiolate complexes [(CH~3~C~5~H~4~)~2~Sm(μ‐SPh)(THF)] ~2~ (1) and Sm(SPh)~3~(HMPA)~3~ (2) as initiators has been investigated for the first time. Both of 1 and 2 were found to be highly efficient ini
## 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
Polymerization of 1-caprolactone had been investigated with cyclopentadienyl sodium as an initiator. The effects of reaction time, temperature, and concentration of the initiator on the yield and molecular weight of the polymer were discussed. It was shown that the high molecular weight of poly(1-ca
