Reaction Steps
44 Grams of p-xylylene-bis-(methylphosphinic acid) are heated to 240° C., and phosgene is slowly introduced, while stirring. In the course of 1.5 hours the temperature is reduced to 210° C. Subsequently nitrogen is passed through the mixture at this temperature. 41 Grams of p-xylylene-bis-(methylphosphinic acid)-anhydride are obtained which have a solidification point of from about 165° to 175° C.
