Semi‐interpenetrating polymer network (semi‐IPN) and IPN systems based on poly(D,L‐lactide) and a functional vinylic polymer can be effectively used as nanostructured precursors to novel functionalized (meso)porous networks. Indeed, the extraction of uncross‐linked oligoesters from semi‐IPNs as well as the quantitative hydrolysis of the polyester sub‐network associated with semi‐hydrolyzable IPNs constitute straightforward and versatile strategies for engineering (meso)porous cross‐linked polymers with miscellaneous functionalities. The versatility of both complementary routes was illustrated through the generation of methacrylic porous networks with acidic (COOH, SO 3 H) functions as well as styrenic porous networks with acidic (COOH, SO 3 H) or basic (pyridine) functions. The potentialities afforded by the two approaches were discussed, and more particularly the porous networks derived therefrom were characterized by several physico‐chemical techniques.
