The functionalization and copolymerization of recyclable polymers allow for the control of properties and broad applications.
Recyclable polymers offer a great opportunity to address the environmental issues of plastics. Herein, functionalization of recyclable polymers, poly ((R)-3,4-trans six-membered ring-fused GBL) (P ((R)-M)), were reported via end-group modifications and block/random co-polymerizations. Di-n-butylmagnesium was selected to catalyze ring-opening polymerization (ROP) of (R)-M in the presence of a series of functional alcohols as the initiators. Block/random copolymerizations of (R)-M and epsilon-caprolactone (epsilon-CL), L-lactide (L-LA) and trimethylene carbonate (TMC) were performed to control the onset decomposition temperature (T-d), melting temperature (T-m) and glass transition temperature (T-g). These functionalized recyclable polymers would find broad applications as the sustainable plastics. (C) 2020, Institute of Process Engineering, Chinese Academy of Sciences.
