Biodegradable poly(lactic acid)‐grafted amylose was synthesized using a trimethylsilyl (TMS) protection method. Tetrahydrofuran soluble, mostly trimethylsilyl protected amylose was prepared and reacted with potassium tert ‐butoxide to give the corresponding alkoxide. Poly(lactic acid)‐grafted amyloses were obtained by ring‐opening anionic polymerization of lactide using the polymeric alkoxides as initiators and subsequent removal of the TMS groups. The obtained graft copolymers show biodegradability and a microphase‐separated morphology.
