摘要：

(Chemical Equation Presented) Pick your polymer: The reactivity ratios, r, of the comonomers can be controlled by the configuration of the active species in the copolymerization of ε-caprolactone (CL) and L,L-lactide (LA; see scheme). Thus, by varying the configuration of the initiator, a broad spectrum of copolymers with different microstructures, from gradient to more random, can be prepared in a controlled way. © 2008 Wiley-VCH Verlag GmbH & Co.
