- *Abstract
-
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 and structural stability, and increased decomposition temperature, in comparison to polymer compositions that lack graft polymers. Other benefits include decreased heat release rate, decreased mass loss rate, decreased peak and average smoke production, and decreased production of carbon dioxide.The invention features nanocomposite compositions that include a graft polymer and nano-sized silica. The nanocomposite compositions can further include another non-graft polymer. The polymers can include one or more polyolefins (e.g., polypropylenes), polydienes, polyacrylates, polystyrenes, polysiloxanes, polyethers, poly(vinyl aromatics), poly(vinyl halides), epoxies, polycarbonates, silicones, polyesters, synthetic rubbers, polyurethanes, nylons, polyketones, or poly(phenylene oxides). The nano-sized silicas can be fumed silica, colloidal silica, or fused silica. US Patent No. 8,143,339. http://patft.uspto.gov/netacgi/nph-Parser?patentnumber=8143339.
