Abstract: Polyphosphate compositions are produced by a process that includes the steps of continuously introducing a phosphate compound into a polymerization vessel, polymerizing the phosphate compound at a temperature of 250-450° C. for a time period sufficient to form the polyphosphate composition, and continuously discharging the polyphosphate composition from the polymerization vessel. The phosphate compound can be fed to the polymerization vessel in the form of an aqueous slurry containing 5-50 wt. % of the phosphate compound. Resulting polyphosphate compositions often contain at least 8 wt. % of a polyphosphate and less than 35 wt. % of the phosphate compound.

Abstract: This invention describes resins with phosphate cores and a simple, three-step process for their synthesis. Preferred resins are cyanate ester resins with bridging phosphate groups. These resins can be cured to produce thermoset polymers having Tgs of between 131 and >360° C. depending on the number of cyanate ester groups per phosphate and the substitution pattern of the aromatic rings. The high char yields of these resins, up to about 67%, coupled with the phosphate core means that these materials will have applications as fire-resistant polymers. Additionally, these materials can potentially be blended with conventional cyanate esters or other compatible thermosetting resins to improve the fire resistance of composite materials. Other applications may include use in fire-resistant circuit boards, or as surface coatings to reduce flammability of conventional composite materials or thermoplastics.
