Abstract
By the oxidation of some alkylene aromatic oligomers under soft conditions we succeeded in introducing into them peroxide-type groups containing active oxygen. Such oligomers may be used as explosion-proof initiators of radical polymerization of vinyl monomers. In addition to initiation, similar oligomers can act as agents, modifying the properties of the polymers obtained. Oxidation in different solvents of poly (phenylene toluylene ethers) (PPTE), obtained by condensation of difterent substitutes of diphenyl ether of general formula X-CH2 , where X = Cl, OH, OCH3, OC2H5, and Y = H or CH2 X, allows the introduction 0.2–0.5% of active oxygen into them. Stability of peroxide groups in oxidized PPTE has been estimated under various conditions. The initiating activity of oxidized PPTE in polymerization of styrene at 80° is arranged in succession depending on the nature of the X substitute: OCH3 > OC2H5 > Cl.
