Extruded polymer foams containing brominated 2-oxo-1,3,2-dioxaphosphorinane compounds as flame retardant additives

Extruded polymer foams are prepared using 5,5-bis(bromomethyl)-2-oxo-l,3,2- dioxaphosphorinane or brominated 2-oxo-l,3,2-dioxaphosphorinane compounds. The brominated FR additives unexpectedly are stable at the extrusion temperatures, and provide excellent flame retardancy to the foams.
