Fluoride recovery in degradable fluorinated polyesters
Summary
Researchers synthesized a new class of degradable fluorinated polyesters by copolymerizing tetrafluorophthalic anhydride with propylene oxide or trifluoropropylene oxide, achieving up to 20 times faster degradation than non-fluorinated equivalents. The materials also allow fluoride recovery, offering potential for more sustainable use of fluorinated polymers.
We report a new class of degradable fluorinated polymers through the copolymerization of tetrafluorophthalic anhydride and propylene oxide or trifluoropropylene oxide which show up to 20 times quicker degradation than the non-fluorinated equivalents and allow for fluoride recovery.

Fast Hydrolyzable Constitutional Isomer of Poly(butylene terephthalate) and Its Copolyesters with 1,4-Butanediol
Researchers developed a fast-hydrolysable polyester designed to degrade more rapidly in the environment than conventional plastics like PET, with the goal of reducing long-term plastic pollution. The new material broke down much more quickly in water while still maintaining acceptable mechanical properties for practical use. Truly biodegradable plastics that fully degrade could help reduce microplastic accumulation in the environment.
