Process stabilization of polymer compositions comprising phosphorous containing flame retardants

Flame retardant polymer compositions comprising certain polymers, a flame retardant material obtained by heating certain phosphonic acid salts at temperatures over 200° C. and certain clays or metal compounds such as select metal borates, oxides, hydroxides, oxide hydroxides etc., are readily processed at elevated temperatures and under high stress conditions whereas similar compositions without the clays or metal compounds of the invention are prone to decomposition. For example, polyamide compositions comprising the flame retardant material obtained by heating certain phosphonic acid salts at temperatures over 200° C., hydrotalcite clays, and/or borates, oxides, hydroxides, oxide hydroxides of zinc or calcium, are highly stable to thermal processing under strenuous conditions such as high temperature extrusion.
