BioDegmer® PGDLLA Poly(glycolide-co-DL-lactide)
Poly(glycolide-co-lactide) (PGLA) is obtained by the ring-opening co-polymerization of glycolide (cyclic dimer of glycolic acid) and lactide (cyclic dimer of lactic acid) as monomers.
Since lactide has 3 optical isomer as L-lactide, D-lactide, and DL-lactide, the copolymer of glycolide and L-lactide is abbreviated to PGLA, while the copolymer of glycolide and DL-lactide is abbreviated to PGDLLA.
