Notes:
High-molecular-weight copolymers of L,L-lactide with ε-caprolactone were synthesized using initiators containing aluminium and zinc, i.e., AlEt2OEt, ZnEtOiPr, Al(acac)3 and AlEt3 + ZnEt2 + H2O. The chain microstructure was revealed to vary from random to diblock arrangement, depending on temperature and the kind of initiator used. In case of Al(acac)3 as initiator, the reactivity ratios of L,L-lactide and ε-caprolactone were determined to be rL = 44 and rC = 0,28, respectively.
