Abstract
Halogenated compounds of the formula ##STR1## wherein each X is independently selected from the group consisting of hydrogen, chlorine, bromine and fluorine, each X.sub.1 is independently selected from the group consisting of hydrogen, chlorine, bromine, fluorine and alkyl or alkoxy of 1 to 10 carbon atoms and halogen-substituted alkyl or alkoxy of 1 to 10 carbon atoms and each Y and Y.sub.1 is independently selected from the group consisting of hydrogen, chlorine, bromine, fluorine, aryl, alkyl or alkoxy of 1 to 10 carbon atoms and halogen-substituted alkyl or alkoxy of 1 to 10 carbon atoms, and a process for preparing these compounds are provided. These compounds are useful as flame retardant additives for various polymers.
