Abstract
On the basis of the data of IR spectroscopy and X-ray phase analysis, it was established that poly-N-vinyl pyrrolidone enters chemical interaction with organic acids during their joint mechanical activation. The character of this interaction depends on the nature of an acid but does not depend on the type of activator, while the duration of the interaction depends both on the nature of an acid and on the type of activator.
