The collection of articles systematizes the results of scientific research on the mechanism of protonation of some styrene. To obtain conventional cationic polystyrene, it is important to know the mechanisms of elementary acts , since it is this knowledge that will allow us to obtain styrene polymers with predetermined properties , This, in turn, is ,. You need to know CM. for example, when using cationic polystyrene as a heat insulator of various concretes. The obtained energy characteristics (energy barriers, thermal effects) can contribute to the production of such polystyrenes, which will regulate the thermal insulation properties of polymer concretes. The collection of articles is intended for young scientists, researchers, students, graduate students, doctoral students and professors specializing in the chemistry of polystyrene and polymer concrete .
