Biodegradable cyclic polyesters are synthesized by using an ε‐caprolactone polymerization initiated by a cyclic tin alkoxide, followed by the addition and sequential polymerization of a few units of α‐(1‐acryloxyethyl)‐ε‐caprolactone. Tadpole‐shaped polyesters with two tails of controllable length are readily prepared by this procedure (see picture).
