実験手順

A mixture of 571 g. of tris(2-chloroethyl)phosphate and 531 g. of dimethyl methylphosphonate was heated at 181°-197° C. until 287.5 of methylchloride was evolved; this required 26 hours. The product was then heated at 95° with 28.2 g. of methenol, and finally treated with ethylene oxide at 90°-100° until substantially neutral. The product was useful as a flame retardant at 5-10 phr. in a styrenated polyester.
