Application

3-Methyl-6-propargyl-1,4-dioxane-2,5-dione is a functionalized biodegradable monomer that can be polymerized using ring-opening polymerization to yield polylactide with a pendant alkyne functionality. This pendant group can be used to further functionalize the polymer or as a backbone for graft copolymer synthesis.
