摘要:
A flame retardant polymer composition comprising at least one polymer and a hypophosphite salt is disclosed, wherein: - the hypophosphite salt is so heat stabilized that, when it is heated for 3 hours at 298℃ 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; and - the flame retardant polymer composition further comprises at least an additive improving the flame retardant properties of the composition.
