More Information
Summary:A novel flame retardant composition is provided wherein the major component is a triphosphate ester of the formula: wherein R represents an alkylene radical of from 2 to about 10 carbon atoms and the halosubstituted derivatives thereof, R' represents an alkylene radical of from 2 to 3 carbon atoms, X represents a halogen of chlorine or bromine, and n is an integer of from 1 to 5. In the preferred composition, R is ethylene or propylene and R' is ethylene, X is chlorine and n is 1. The compositions are less fugitive than the prior art diphosphate compositions yet easier to prepare than low volatility phosphates presently manufactured by polycondensation.
