<p>Disclosed are halobenzene sulfonates of the generic formula wherein X snd X' are independently selected halogens, preferably chlorine and bromine; n is an integer of from 1 to 5; R is an alkyl or alkenyl of from 3 to about 8 carbon atoms; Z has a value of O if Y-Y'-O and a value of from 1 to L if Y-Y'> O, wherein L Y-Y'+W, with Y being the number of primary, secondary, and tertiary carbon atoms in R, Y' being the number of primary, secondary, and tertiary carbon atoms in R containing a halobenzene sulfonate substitutent, and W-A-B wherein A is the number of replacable hydrogen atoms present in the primary, secondary and tertiary carbon atoms in R devoid of halobenzene sulfonate substituents and B is the number of primary, secondary and tertiary carbon atoms in R devoid of halobenzene sulfonate substituents; and m is an integer of from 2-4, provided that m is an integer of from 1-4 when k is a neopentyl group. Also disclosed are polymeric compositions containing these compounds as flame retardant additives.</p> |
