FIELD: organic chemistry. SUBSTANCE: product: 2-[3-(N,N,N-trialkylammonio)-propionamido] -2-methylpropanesul- -fonates of the general formula 
where: R3N - (CH3)3N, (CH3)2NCH2CH2OH, (CH3)2N(CH2)3NHCOC(CH3)=CH2, (CH3)2NCH2CH2C(CH3)2NHCOC(CH3)=CH2, CH3N(C2H5)2, (C2H5)3N, N(CH2CH2)3N. Method involves interaction of tertiary amines with 2-acrylamido-2-methylpropane sulfoacid in an aqueous medium followed by isolation of the end product by solvent and unreacted parent substances removing. Process is carried out at mole ratio of tertiary amine and 2-acrylamido-2-methylpropane sulfoacid = (1.02-2.10): 1.00. EFFECT: improved method of synthesis. 2 cl, 1 tbl
