Fabrication of a weakly basic chemisorption fibre with aliphatic amino groups

The conditions for fabrication of an anion-exchange fibre with primary and secondary amine groups by preliminary treatment of Nitron fibre with an aqueous solution of hydroxylamine. The effect of the chemical nature of aminating reagents—hydrazine hydrate, ethylenediamine, and triethylenetetramine—on formation of aliphatic amine groups in Nitron fibre was investigated. It was hypothesized that the kinetics of amination is a function of the basicity of the aminating reagent.
