Polyaminated derivatives of polychloropolyphenylbenzenes
Abstract
Abstract A polyaminated derivative of polychlorinated polyphenylbenzenes higher than diphenyl, useful as an anti-ignition additive in polymer-type materials such as polyesters and having a general formula: PREPARED AT A TEMPERATURE BETWEEN 70* AND 300* C. by the reaction of an aminated compound containing members R1Z and R2Z with at least one polyhalogenated polyphenylbenzene R1Z and R2Z are members selected from the group consisting of an atom of hydrogen and a functional group formed by a radical R1 and R2 and by a terminal group Z, said radicals R1 and R2 being selected from the group consisting of a saturated aliphatic having from two to eight carbon atoms and an aromatic, said terminal group Z being a member selected from the group consisting of -OH, -NH2, CH3.
