Abstract
Abstract This invention deals with new phosphorus-containing esters having the formulas wherein Y represents H, CH3 or Cl; R represents a divalent hydrocarbon radical containing one to twenty carbon atoms; Q represents R'' represents X, hydrogen or R''''; R'''' represents a monovalent hydrocarbon radical containing one to twenty carbon atoms; and X represents chlorine or bromine. These new esters are useful particularly as fire retardants, agricultural chemicals, fuel additives, plasticizers, monomers and intermediates for the synthesis of other useful derivatives.
