Title:
FLAME RETARDANT PRECURSORS, POLYMERS PREPARED FROM SUCH PRECURSORS, AND FLAME RESISTANT FABRICS TREATED WITH SUCH POLYMERS
Document Type and Number:
WIPO Patent Application WO/2015/061586
Kind Code:
A3
Abstract:
A composition comprises at least one condensed phosphorus compound. The condensed phosphorus compound is produced by reacting together in a condensation reaction a nitrogen compound and a phosphonium compound. A phosphorus-containing polymer is produced by reacting in a condensation reaction a hydroxyalkylphosphonium compound to produce an intermediate polymer and then oxidizing phosphorus atoms in the intermediate polymer to yield a polymer comprising phosphine oxide groups.
