摘要: A flame retarded, injection moldable, saturated, linear polyester composition contains red phosphorus as flame retardant and a metal iodide as phosphine suppressing agent. The metal is one of the groups 1a and 2b of the periodic table of elements with potassium iodide being the most preferred.The phosphine evolution of a poly(ethylene terephthalate) molding composition containing 4% red phosphorus as flame retardant is reduced to 0.3 ppm at the die and to 1.0 ppm in storage by the addition of 0.6% of potassium iodide.
