Abstract: Halogen-free flame retarded unsaturated polyester (UPE) composites are described, where aluminum methyl methylphosphonate (AMMP) was added to a UPE matrix in order to obtain a UL94-V0 formulation. The combustion properties of AMMP are improved to that of aluminum trihydrates (ATH) in cone calorimetry. The use of AMMP prepared with phosphonium catalyst was also shown to be advantageous for retaining the gelation time of the UPE resins in a mold.
