Abstract
Abstract Polymeric compositions comprising a polyolefin polymer and a flame retarding amount of a compound of the formula ##STR1## wherein each R is independently selected from a group consisting of hydrogen, alkyl, halogenated alkyl, phenyl, and halogenated phenyl groups, said alkyl groups containing from 1 to about 6 carbon atoms and said halogenated groups containing from 1 to about 5 halogen substituents per group, said halogen substituents selected from a group comprising chlorine and bromine; wherein X is selected from a group comprising chlorine and bromine; and wherein n is an integer from 1 to 3, and mixtures thereof.
