The higher rate and depth of the hydrolysis and amine methylation reactions in PVA-PAAN graft copolymers comparing with PAA was established. The effect of strengthening of intramolecular interactions in PVA-PAAN anionic derivatives in H-form with increase of hydrolyses degree was revealed. The product of amine methylation reaction is polyampholite with preferring contents of tertiary amine groups. The more homogeneous bulk structure of SiO2-PAAN polymer-inorganic compound comparing with PAA was established. The high flocculative capability of PVA-PAAN cationic derivatives was revealed.5635
