  • Patent number: 4959500
    Abstract: Described are polybromoaromatic bis-sulfonamides containing at least two bromoaromatic groups, from 18 to 30 carbon atoms (preferably 18 to 24), and from 6 to 14 bromine atoms substituted on the aromatic rings. Such polybromoaromatic bis-sulfonamides may be represented by the general formula ##STR1## where Ar are the same or different polybromoaromatic groups, R is a divalent aromatic or bromoaromatic group, and R' and R" are independently hydrogen atoms, hydrocarbon groups or halohydrocarbon groups in which the halogen atoms are chlorine or bromine, the total number of bromine atoms substituted on the aromatic rings of the groups designated as Ar and R falling in the range of 6 to 14. These sulfonamides are useful as flame retardants and plasticizers for thermoplastic polymers and have the advantage of relatively low volatilities at polymer processing temperatures.
