Abstract

Procedeu pentru obtinerea unor copolimeri modificati, cu actiune radioprotectoare, caracterizat prin aceea ca, în scopul asigurarii unei actiuni de protectie, cu remanenta îndelungata se efectueaza reactia dintre copolimerul N-vinilpirolidona-anhidrida maleica cu derivati fosforici de 2-aminoetantiol, alesi dintre sarea monosodica a acidului S-[2-(3-aminopropil)aminoetil] tiofosforic, în raport echimolar, în solvent N-metilpirolidona, la temperatura de 40...50 degree C.Process for obtaining modified copolymers having radioprotective action, characterized in that in order to provide a protective action with a long residence time, the reaction between the copolymer of N-vinylpyrrolidone-maleic anhydride and the 2-aminoethanethiol phosphoric derivatives selected from the monosodium salt of S- [2- (3-aminopropyl) aminoethyl] thiophosphoric acid in an equimolar ratio in N-methylpyrrolidone at 40-50 ° C.
