glycolide is white flake crystals, impure glycolide is pale yellow, The melting point is about 84 ° C and glycolide is soluble in ethyl acetate. The boiling point of 330 ° C. The oil pump can be obtained by vacuuming 220 °C.

There are two ways to synthesis glycolide. The first route is that the glycolic acid molecules are mutually reacted and dehydrated to form a lower molecular weight polyglycolic acid, and the polyglycolic acid is pyrolyzed and cyclized to form glycolide. The second route is to remove the metal halide by using a metal salt of a haloacetic acid such as potassium to form a glycolide.

As the monomer of glycolide polymerization, glycolide can be homopolymerized to obtain polyglycolide or ring-opened copolymerization with other cyclic monomers. This plays an important role in the research and development of medical polymer materials. Glycolide has been applied in many fields such as surgical sutures, artificial skin, blood vessels, bone fixation and repair, drug controlled release, and tissue engineering.
