The effects on radical polymerizations of some compounds containing double bonds involving nitrogen

Abstract

The Schiff bases formed by condensation of aromatic aldehydes with aniline seem to induce the decomposition of benzoyl peroxide in solution. Benzaldehyde azine has very little effect of any type on the polymerization of methyl methacrylate. Benzaldehyde benzylamine is a retarder for the polymerization; the effect is much greater when benzoyl peroxide acts as initiator than when azobisisobutyronitrile is used. It has also been shown that azobenzene is a mild retarder for the radical polymerization of methyl methacrylate and that it has slight reactivity towards the benzoyloxy radical; the retarding effect is almost the same when using benzoyl peroxide as when the azonitrile is employed.
