Graft polymerization of methacrylic acid to polycaproamide, initiated by the K 2 S 2 O 8 Na 2 S 2 O 3 Cu 2+ reversible redox system, has been studied. Kinetic characteristics of graft polymerization have been investigated in a wide concentration range of every component of the initiating system. Cu 2+ ions have been found to catalyze graft polymerization in the 1.0 · 10 −5 −1.2 · 10 −4 M concentration range, whereas at concentrations higher than 1.2 · 10 −4 M , Cu 2+ ions are involved in the kinetic chain termination. A mechanism of graft polymerization is proposed. © 1993 John Wiley & Sons, Inc.
