NOVEL METAL HYDROXIDE DERIVATIVES CONTAINING CHEMICALLY BOUND ORGANOPHOSPHORUS OR POLYPHOSPHATE SPECIES AS FLAME RETARDANTS

摘要

Novel metal hydroxide derivatives which chemically combine positively charged metal hydroxide layers with negatively charged phosphorus-containing species, which can be either anionic organophosphorus materials or phosphorus-containing polymeric anions, are described. The metal hydroxide derivatives are useful flame retardants through their ability to be completely dispersed and their formation of a crust or char to prevent flame propagation.
