Kinetic study of vinyl polymerization with a new oligo azo peroxidic initiator

Oligo (4,4'-azobis-cyanopentanoyl-5-peroxy-2,5-dimethyl-n-hexylperoxide), Lu-Ab, was synthesized by the interfacial condensation of 4,4'-azobis-(4-cyanopentanoyl chloride) with 2,5-dimethyl-2,5-dihydroperoxyhexane in the presence of a base. The molecular weight of the initiator was determined to be 1586 g/mol by gel permeation chromatography (GPC). Oligo-azoperoxide, Lu-Ab, was characterized by infrared and nuclear magnetic resonance spectroscopies.
