N2 - The sulfonation of polyamides (Nylons‐3,6,11 and 6,6) was investigated using fuming sulfuric acid and solutions of SO3 in CCl4. The sulfonated polymers were soluble in water and insoluble in ethanol. Acid hydrolysis of the polymers and quantitative determination of the amino acids in the hydrolysate showed the presence of α‐sulfo amino acids. This showed that sulfonation in the polymer occurred in the active α‐position of the amide group.
