Almtraet--A photometric method is developed for the determination of the molar mass of 2,4-ionene by attaching a chromophoric moiety to its end-groups. Molar mass determination of these polyelectrolytes by acid-base titration of the amine end-groups is also possible, and confirms the photometric met
