ABSTRACT:
A filler material for use in a polymer or paper system. The filler material is formed by heating hydrotalcite to less than approximately 600.degree. C. to remove most of the carbonate and water of hydration; submersing the hydrotalcite in a NaBr solution for 1-24 hours in a nitrogen atmosphere to form a bromide intercalated hydrotalcite; and adding the bromide intercalated hydrotalcite as a 25-65 wt % filler in a polymer system selected from the group of polypropylene, polybutylene terephtalate, nylon, and acrylonitrile-butadiene-styrene.
