Abstract

Certain phosphorus- sulfur compounds are effective in reducing the LOI of combustible organic polymers and in providing better FR characteristics to the polymers as determined by other standardized tests. The phosphorus-sulfur compounds are sulfur-bridged, metal-bridged or in the form of salts such a ammonium, sulfonium or phosphonium salts.
