M. Bero et al., SYNTHESIS OF BLOCK-COPOLYMERS OF EPSILON-CAPROLACTONE AND LACTIDE IN THE PRESENCE OF LITHIUM T-BUTOXIDE, Polymer bulletin, 31(1), 1993, pp. 9-14
High molecular mass copolymers with microphase separation can be obtai
ned in block copolymerization of epsilon-caprolactone with L,L- and D,
L-lactide carried out in the presence of lithium t-butoxide. A kind of
solvent applied strongly affects the molecular mass and polydispersit
y index of obtained copolymers.
