## Abstract Biodegradable copolymers were prepared by ring‐opening polymerization of sequentially added __ε__‐caprolactone and DL‐lactide in the presence of ethylene glycol or poly(ethylene glycol), using zinc metal as catalyst. Polymerization was performed in bulk and yielded block copolymers with
## Abstract The cationic polymerization of L‐lactide and ϵ‐caprolactone initiated by methyl trifluoromethanesulfonate in nitrobenzene was studied. The monomer conversion and the average molecular weight decrease when the temperature increases. The kinetics constants for L‐lactide and ϵ‐caprolactone
