Copolymerization of γ‐butyrolactone (γBL) with ε‐caprolactone (εCL) initiated with aluminium isopropoxide trimer ([Al(O i Pr) 3 ] 3 , (A 3 )) is described. Copolymers with molecular weights ( M n ) up to 3 · 10 4 and containing up to 43 mol‐% repeating units derived from γBL are prepared. Their molecular weight is controlled by the concentrations of the consumed comonomers and the starting concentration of initiator { M n = (86.09 · [γBL] c + 114.14 · [εCL] c )/3[Al(O i Pr) 3 ] + 60.10}. 13 C NMR and DSC data are indicative of a pseudoperiodic or random copolymer structure.
