Abstract:  The paper is concerned with the synthesis and characterization of a new bifunctional initiator — 4,4'-azo-bis(4-cyanovaleryl)-4-nitrobenzoyl diperoxide. The synthesis was performed starting from the acid chloride of the 4,4'-azo-bis(4-cyanovaleric) acid which was condensed with 4-nitroperbenzoic acid. The kinetic study of the thermal decomposition of the initiator yielded the establishment of the decomposition rates, activation energies, and half-life time. The new initiator was used to obtain poly(styrene-b-acry!ic acid) copolymers.
