Abstract (English):
The formation of stable complexes of hydrogen peroxide and poly-N-vinylpyrrolidone, for which H 2O 2 desorption occurs at temperature from 94,7 to 110,0 0C depending on the composition of the mixture, was experimentally shown. The binding energy of N-vinylpyrrolidone - hydrogen peroxide and N-vinylpyrrolidone - water was determined by quantum chemical calculations. The structure of complexes formed by N-vinylpyrrolidone and a chain of H 2O 2 molecules was considered. The calculation results are in agreement with the fact that the polymer forms stable complexes with H 2O 2 that are able to cause steric hindrances for the chemical reactions (destruction) of molecules, such as tetrapyrroles, associated to the polymer.
