Abstract

The effect of the character of the medium on the occurrence of the heterogeneous reaction of amination of PVA-PGMA graft copolymers with polyethylenepolyamine was investigated, A kinetic effect was established when polyethylenepolyamine solutions were used. The effect of the solvent on the completeness of the reaction of PGMA α-oxide groups with polyethylenepolyamine amino groups, caused by swelling of the solid phase of the polymer and a change in the reactivity of the functionally active groups of the reacting compounds, was demonstrated.
