Poly(glycolide) polymers are disclosed. The polymers generally include a polymerized alkynyl-substituted glycolide having a polymer backbone with one or more alkynyl groups appended thereto. The alkynyl groups provide reactive sites for further functionalization of the polymer, for example by reaction with azide derivatives (e.g., azide-substituted organic compounds). Alkynyl and azide groups react via the “click” chemistry mechanism to form functional groups covalently bonded to the polymer via a triazole link. The polymers are biodegradable and can be used to deliver drugs or other therapeutic substances (e.g., large biomolecules such as single strand RNA) at targeted locations in a patient's body and/or at controlled release rates.
