摘要： A flame retardant polymer composition is described. The composition includes at least one polymer and a hypophosphite salt, wherein the hypophosphite salt is heat stabilized so that when it is heated for 3 hours at 298° C. under a flow of argon flushing at rate 58 mL/min, it generates less than 0.5 mL of phosphine per gram of hypophosphite salt. The flame retardant polymer composition can also include at least one additive that improves the flame retardant properties of the composition.

摘要： The current invention relates to a process for stabilizing a hypophosphite salt, comprising the step of heating the hypophosphite salt at a temperature of between 150 and 370° C. during a sufficient period of time to prevent the formation of a dangerous quantity of phosphine in their application as FR in polymers and a flame retardant polymer composition comprising a polymer and 0.1 to 30 weight percent based on the total weight of the composition of the hypophosphite salt thermally stabilized by the above process.
