Abstract: Abstract A novel phosphorus-nitrogen flame retardant, nano zirconium amino-tris-(methylenephosphonate) (Zr-AMP), successfully synthesized by allowing amino trimethylene phosphonic acid (AMP) to react with ZrOCl·8H2O, was incorporated into rigid polyurethane (RPU) foam with expandable graphite (EG) to… read more here.
