  • Patent number: 8362127
    Abstract: A halogenated non-polymeric phenyl ether flame retardant is described having the general formula (I): wherein each X is independently Cl or Br, n is an integer of 1 or 2, and each p is independently an integer of 1 to 4, provided that, when each X is Cl, the total amount halogen in the ether is from about 50 to about 65 wt % and when each X is Br, the total amount halogen in the ether is from at least 70 wt % to about 79 wt % and wherein from about 30% to about 80%, for example from about 35% to about 75% of the halogenated ethers are fully halogenated the remainder being partially halogenated. The present flame retardant provides superior mechanical properties when incorporated into a polymer than similar flame retardants which contain a higher amount of fully halogenated species.
