Abstract

(Pentaerythritol phosphate alcohol)(cyclic neopentylene glycol) phosphite and phosphonate are disclosed as flame retardant compounds. The first named compound is formed by the reaction of pentaerythritol phosphate alcohol with a neopentylene glycol halophosphite, such as neopentylene glycol chlorophosphite. The (pentaerythritol phosphate alcohol)(cyclic neopentylene glycol) phosphonate is formed by heating (pentaerythritol phosphate ol)(cyclic neopentylene glycol) phosphite.
