New patent: Nanocomposite compositions containing a graft polymer and a filler such as nano-sized silica having flame resistant properties

This patent was published on March 2012.


The invention is based, at least in part, on the discovery that by mixing graft polymers with a nano-sized hydrogen-bonding filler such as silica, one can obtain nanocomposite compositions that have a much higher flame resistance, increased char formation, greater structural stability of char, increased decomposition temperature, decreased heat release rate, decreased mass loss rate, decreased peak smoke production, decreased average smoke production, and/or decreased production of carbon dioxide, than in polymer compositions that lack graft polymers.
