The present paper reports on the systematic hydrolysis kinetic studies of the monomer N-vinylbenzylidene-3-aminopyridine Im and its corresponding copolymers Cpa and Cpb. These studies were established in homogeneous media with pH range from 4 to 10 using UV-Vis spectrophotometer for analysis. The experimental kinetic constants were calculated and a hydrolysis mechanism was proposed. The pH-rate diagram profile was also determined for the monomer and copolymers.
