Abstract

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.

## Abstract The synthesis of a water‐soluble azo initiator was performed in four steps: action of hydrazinium sulfate onto 4‐phenylbutan‐2‐one followed by an addition of hydrogen cyanide onto the azine, then oxydation with bromine and finally chlorosulfonation of the obtained aromatic azo compound.
