CATIONIC POLYELECTROLYTES .9. NEW ASPECTS OF POLY(N,N-DIALKYLAMINOALKYLACRYLAMIDES) SYNTHESIS VIA NITRILE GROUP REACTION OF POLYACRYLONITRILE WITH N,N-DIALKYLAMINOALKYLAMINES

The aminolysis-hydrolysis of the nitrile groups of PAN with asymmetrical diamines as H2N-(CH2)m-NR2 was investigated by IR spectroscopy (qualitative and quantitative) and elemental analyses. IR quantitative spectroscopy is an adequately proved method for investigation of the extent of transformation. The amine reactivity depends on the distance between the two amine groups and the size of the alkyl substituents on the tertiary amine. The data support the reaction mechanism by the nucleophilic attack of the primary amine on the two neighbouring nitrile groups.
