poly(γ-butyrolactone) PGBL

Chemical formula

(C4H6O2)n

General description

poly(γ-butyrolactone)  (PGBL)

  • only commercially available from us
  • non-toxic and fully biodegradable polyester
  • the highest hydrolytic biodegradation time among other polyesters
  • good compatibility with a wide range of polymers

Our innovation in the production of PGBL

Our innovative high-pressure strategy involving TBD-catalyzed ROP allowed us to produce well-defined linear and star-shaped (4-arms) PGBLs of high chain-end fidelity.
