Abstract
A synthesis method of new fibrous anion exchangers with strong base groups has been developed. The synthesis was carried out by alkylation of weakly basic anion exchangers based on polyacrylonitrile fiber using two alkylating agents: epichlorohydrin and ethylene chlorohydrin. The influence of the reaction conditions on the physicochemical properties of new anion exchangers was investigated. The synthesis parameters were determined: the molar ratio of “amino groups: alkylating agent”, the concentration of the alkylating agent, the reaction time and temperature – to obtain anion exchangers with maximum exchange capacity for strong base groups. New strongly basic fibers possess satisfactory mechanical properties allowing their processing into various textile forms.
