Abstract

Summary: We have developed the first direct, organocatalytic, bulk ring‐opening polymerization (ROP) of ε‐caprolactone (ε‐CL) with solid cotton and paper cellulose as the initiators. The mild ROPs were performed without solvent, and are operationally simple, inexpensive and environmentally benign. Organic‐acid‐catalyzed heterogeneous derivatization of cellulose provides a novel route to valuable cellulose‐based biocompatible nanomaterials. The furnished polymerization products were characterized by FTIR, ^1^H and ^13^C NMR spectroscopy, MALDI‐TOF mass spectrometry and electron microscopy.
