| Popis: | The interaction of phenol with graft copolymers of poly(acrylamide) to poly(vinyl alcohol) (PVA-PAA N ) forming intramolecular polycomplexes (Intra PC), and also with PAA, is investigated by the methods of gel chromatography, viscometry, UV and IR spectroscopy. It is shown, that phenol connection with polymers is weak and carried out on the equilibrium mechanism. Under phenol influence the effect of compacting of polymer macromolecules is observed. It is revealed, in particular, by change of the ratio between different H-bonds structures in polymer films obtained at phenol presence. PVA-PAA N connect phenol more effectively, than PAA; the quantity of bound phenol grows with N. |
