1,4-Dioxane-2,5-dione is used in the fabricating of artificial blood vessels. | [General Description]
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. | [Flammability and Explosibility]
