Abstract
Procedure for the preparation of a fire-retardant phosphonate composition, especially suitable as a fire-retardant agent for polyurethane foam materials, characterized by reacting pentaerythrite with 2 to 4 moles of dimethyl methaphosphonate at a temperature of 50 to 200ºC and eventually treating the mixture afterwards reaction at a temperature of 40 to 100ºC with an alkylene oxide.
