Oligomerization of thiol‐unprotected l ‐cysteine ethyl ester (Cys‐OEt) catalyzed by proteinase K in aqueous solution has been used to synthesize oligo( l ‐cysteine) (OligoCys) with a well‐defined chemical structure and relatively large degree of polymerization (DP) up to 16–17 (average 8.8). By using a high concentration of Cys‐OEt, 78.0% free thiol content was achieved. The thermal properties of OligoCys are stable, with no glass transition until 200 °C, and the decomposition temperature could be increased by oxidation. Chemoenzymatically synthesized OligoCys has great potential for use as a thermostable bio‐based material with resistance to oxidation.
