摘要

POLYMER FOAM, PROCESS FOR PRODUCING EXPANSIBLE STYREN POLYMERS WITH HALOGEN-FREE FLAME RETARDANT OR EXTRUDED STYLENE POLYMER, POLYMER EXPANSIBLE STYLENE POLYMER IS EXHIBITED halogen free flame retardant polymer foams, and in particular polystyrene particulate foams made from expanded polystyrene (EPS), or extruded polystyrene foam sheets (XPS) containing a phosphorus compound as a flame retardant with formula (I), wherein R 1, R 2 and R 3 independently of each other are H substituted or unsubstituted C 1 -C 15 alkyl substituted unsubstituted or substituted C 1-1 -C 15 alkenyl, substituted or unsubstituted C 3-8 cycloalkyl, substituted or unsubstituted or unsubstituted or substituted C 1-6 aryl substituted C 7 -C 30 alkylaryl, or the product of hydrolysis or metal salt of a phosphorus compound of general formula (I), and a method for producing them.
