Synthesis of poly(l-leucine)
 The invention relates to a method for synthesis of poly(L-leucine). Without any initiator and solvent poly(L-leucine) has been made from L-leucine-N-carboxy anhydride as starting material in the solid state by irradiation with gamma ray. There is only one step in the entire synthetic processing, and the polymerization yield is 100% and the process is a very simple, safe and convenient method. The poly(L-leucine) is one of the best materials for temporary wound dressing.
