AB block copolymers of c-caprolactone and ([.) -lactide could be prepared by ring-opening polymerization in the melt at 110"C using stannous octoate as a catalyst and ethanol as an initiator provided c-caproiactone was polymerized first. Ethanol initiated the polymerization of c-caprolactone produci

## Abstract Biodegradable and photocurable block copolymers of __ε__‐caprolactone and L‐lactide were synthesized by polycondensation of PLLA diol ($\overline {M} \_{{\rm n}} $ = 10 000 g · mol^−1^), PCL diol ($\overline {M} \_{{\rm n}} $ = 10 000 g · mol^−1^), and a chain extender bearing a coumari
## Abstract **Summary:** We report here on the controlled grafting of defined copolyester chains directly onto the activated surface of MMT nanoplatelets dispersed in apolar medium. More precisely, monomers such as CL and LA were copolymerized, in dilute solution, by the well‐known coordination‐ins
