The reaction of oxidative chlorophosphorylation of styrene-butadiene rubber was studied by 1 H, 13 C, and 31 P NMR method. Investigations of functionalized styrene-butadiene rubber were carried out using low phosphorus containing samples selected from reaction medium at regular intervals. The obtained results have been discussed in detail, and make it possible to interpret the mechanism of the reaction and the structure of the polymer obtained.

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.
