ABSTRACT:
The present invention relates to a process for the improvement of the flame retardant properties of a polymer composition which comprises incorporating therein an effective flame retardant amount of a halogenated phospholane oxide. The resultant products are useful as rigid or flexible foams and shaped articles having greatly improved flame retardant and smoke suppressant properties. The use of the halogenated phospholane oxide also imparts stability to the products, thus overcoming difficulties encountered with volatile phosphorus compounds which had been used heretofore with polymeric compositions such as polyurethanes.
