EXTRUDED POLYMER FOAMS CONTAINING BROMINATED 2-OXO-1,3,2-DIOXAPHOSPHORINANE COMPOUNDS AS FLAME RETARDANT ADDITIVES

摘要

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.
