Abstract A new, economic technique was developed for the production of 2‐alkyl‐2‐oxazolines with saturated, unsaturated or OH‐functionalized alkylrests. In the process the fatty acids are changed into polymerizable monomers. The cationic polymerization of fattyalkyl‐2‐oxazolines was investigated in unpolar solvents and in bulk. It reacts in a living mechanism. The polymerization is remarkable inert against impurities like water or ethanolamide. A reaction enthalpy of ΔH = 85,9 kJ/mol was found for the bulk polymerization of 2‐pentadecyl‐2‐oxazoline.
