The object of the invention is a method of producing phosphorus-containing polyesters by polycondensation of phosphoric dichlorides with dioxy compounds. It is different in that, to produce phosphorus-containing polyesters with double bonds along the ends of the chain and also to expand the assortment of unsaturated phosphorus-containing polyesters, chloroanhydrides of an unsaturated acid for example, methacrylic are added to the reaction mixture.
