The synthesis of 2‐acrylamido‐2‐methylpropanoic acid (2A2MPA) was carried out starting from 2‐methylpropanoic acid. Copolymerizations of the 2A2MPA salt (2A2MPANa, monomer A) with acrylamide (AM, monomer B) were investigated using K 2 S 2 O 8 as initiator. They were terminated before reaching 15% conversion. A range of feed compositions was selected (2A2MPANa increasing from 10 to 100 mol‐%) and the compositions of the copolymers obtained were assessed through 13 C NMR. The reactivity ratios for the couple A, B were determined as r A = 0,76 and r B = 1,06. One additional copolymerization was allowed to reach 100% conversion, and the final copolymer showed interesting drag reduction properties.
