Abstract

The present invention provides a phosphorus compound of formula (I).The phosphorus compound is prepared by reacting a compound of formula (II) with alkylene carbonate.As compared with the conventional phosphorus compounds as flame-resistant additives, the phosphorus compound of the present invention has not only a high pyrolysis temperature but also excellent solubility in most of the organic solvents with high or low polarity, and is therefore a suitable flame-resistant additive for use in thermosetting or thermoplastic resins.
