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.
