👉 Monomer design via functionalization serves as a promising strategy towards the development of inexpensive and high-performance chemically recyclable polymers.
👉 We present here a green cyclodepolymerization route for the chemical recycling of poly(ethylene adipate) to its cyclic oligomers based on ring–chain equilibria in solution.

A one-pot approach towards polycarbonate-b-polyester block copolymers via chemoselective polymerization catalyzed by a one-component phosphonium borane Lewis pair
Yutao Li, Xinhui Kou, Xiaowu Wang*（王晓武，青岛科技大学）, Lin Xia*（夏琳，青岛科技大学）and Zhibo Li*（李志波，青岛科技大学）
👉 Chemoselective polymerization from a mixture of L-LA, CHO and CO2 enables the synthesis of PLLA, PCHC or PCHC-b-PLLA achieved by PBB-Br. The chemoselectivity depends on the nature of the growing polymer chain end.
