Abstract
A new polymeric initiator, oligo(adipoyl-5-peroxy-2,5-dimethyl n-hexyl peroxide), was synthesized by interfacial condensation of adipoyl chloride with 2,5-dimethyl-2,5-dihydroperoxy hexane. This can be used as an initiator to prepare block copolymers by free radical mechanism in a procedure involving several steps, since the colorless, viscous liquid, oligoperoxide, has 8–10 peroxide groups per molecule. The thermal decomposition of this oligoperoxide in benzene solution at 98°C was first order and its half life was 9.75 h. The results of the polymerization kinetics show that this oligoperoxide lies in between of 2,5-dimethyl-2,5-dihydroperoxyhexane and benzoyl peroxide for empirical polymerization rates of styrene and methyl methacrylate at 80°C.
