ABSTRACT:
Bauxites are rendered compatible with polymer compositions employed in the carpet industry. Suitable bauxites, which can be employed as flame-retarding fillers, are characterized by a surface area of less than about 12 m.sup.2 /g, a pH in aqueous suspension of more than about 6.5 and a particle size distribution, wherein less than about 15% by weight of the particles have a size of less than 3 microns. Bauxites having a surface area in the range of about 12-20 m.sup.2 /g can also be rendered compatible by modifying their surfaces with a small but effective amount of modifier selected from inorganic phosphates, silicates, aliphatic and aromatic hydroxycarboxylic acids.
