Polymers with tertiary amino groups obtained by the reaction between chloromethylated polystyrene and 3-alkylaminopropionitrile

Polymers with tertiary amino groups were obtained by reaction of chloromethylated polystyrene (CMPS) with 3‐alkylaminopropionitriles (2a — e). The resulting polymers 3a — e were characterized by elemental analyses, IR and 1H NMR spectra. Kinetic investigation showed that the reaction is characterize...

Description
Summary:Polymers with tertiary amino groups were obtained by reaction of chloromethylated polystyrene (CMPS) with 3‐alkylaminopropionitriles (2a — e). The resulting polymers 3a — e were characterized by elemental analyses, IR and 1H NMR spectra. Kinetic investigation showed that the reaction is characterized by two rate constants, the rate change taking place at a conversion of 45–50%. Viscosimetric studies of the hydrochlorides of polymers 3a — e in water and methanol showed that they behave as polyelectrolytes only in methanol. The abnormal behaviour of water solutions was explained by hydrolysis reaction. To prove the conclusions on the molecular structures of 3a — e and the reactivity of CMPS, a study of the reaction of benzyl chloride with the same amines was performed.
