Selective Low-Temperature Depolymerization of Highly Transesterified P(LLA-co-CL) Copolymers: Efficient Lactide Recovery and PCL Upcycling.

The selective chemical recycling of copolyesters remains a major challenge for achieving polymer circularity. Here we show that highly transesterified poly(L-lactide-co-caprolactone) (P(LLA-co-CL)) copolymers undergo low-temperature depolymerization…
