Description générale

Glycolide is a cyclic dimer of α-hydroxy acid that can be used in the formation of aliphatic polyester. It is synthesized by the dimerization of glycolic acid. It forms a low toxic synthetic biodegradable polymer that can be used in medical applications. It is majorly used in the formation of a highly crystalline poly(glycolide) by ring opening polymerization.

Application

Glycolide can be used as a monomer in the preparation of poly(lactic-co-glycolide)(PGLA) via copolymerization with lactide monomer. PGLA is further used in the following applications:
  • Porous PGLA microsphere scaffolds are used in bone repair applications.
  • Encapsulated PGLA nanoparticles can be used in drug delivery and tissue engineering applications. Polymeric micro/nanoparticles made from PLGA have gained significant interest for their appealing characteristics, including biodegradability, biocompatibility, prolonged drug release, and safeguarding the drug against degradation.
It can also be used to synthesize poly(glycolide-caprolactone)(PGCL) copolymers applicable as bioabsorbable suture materials.
