摘要：

The kinetic parameters of the initial stage of the heterophase reaction of α-oxide groups in the graft copolymer of polycaproamide and polyglycidyl methacrylate in different solvents are determined. The significant effect of substitution of a polar hydroxyl-containing solvent by bipolar aprotic solvents on the reaction rate of hydrazidation of PCA-PGMA copolymer is demonstrated and is primarily caused by an increase in the nucleophilicity of hydrazine hydrate due to a change in its solvation and an increase in the diffusion coefficient.
