Acid-Base Properties of Phosphorus-Containing Polymeric Sorbent on the Basis of Polybutadiene-Styrene Rubber

Abstract

The acid-base properties of functional-analytical groups of polymeric sorbent based on butadienestyrene rubber were investigated. The polyfunctionality of the explored sorbent was proved out by the potentiometric titration method and рК ion values of functional-analytical groups were calculated: рК 1 = 4.924; рК = 9.429.

Acid-Base Properties of Phosphorylated Crumb Rubber

“…A positive particularity of the reaction is the opportunity to carried out using easily available commercial reagents under soft conditions on the main laboratory equipment. In previously works we reported the results of studies, where both individual (butadiene rubber [14][15][16][17], styrene-butadiene rubber [18,19], nitrile-butadiene rubber [20]) polymers and polymer mixtures [21] were used as the initial matrix. The obtained products were successfully applied for the preparation of nanocomposites [21,22], adsorbents [23,24], and extractants for the concentration of metal ions by the solid phase extraction method [15,16,22].…”
