ABSTRACT:
Compositions comprising organic phosphorus compounds having a peroxygen group which is either a hydroperoxyalkyl (H--OO--C--) group or a peroxyether (--C--OO--C--) group. There is at least one such group per 500 phosphorus atoms in the composition. These peroxygen compounds may be made by passing oxygen through a liquid comprising a phosphorus compound which has an aliphatic carbon, having an abstractable hydrogen, directly attached to a carbon of an aryl ring; for example, an isopropylphenyl phosphate. The peroxygen compounds may be added to compositions comprising peroxide-reactive organic polymers to increase flame resistance.
