Abstract of the Disclosure There are disclosed a phosphorus-containing polyester and size compositions especially useful for sizing spun and continuous filament yarn produced from hydrophobic fibers and useful in protecting these fibers from abrasion during the weaving process. When the size is used alone or in mixtures with conventional size agents such as starches and polyvinyl alcohol, improved adhesion is obtained to hydrophobic fibers or blends thereof with cotton or other hydrophilic fibers. Polyester, poly- propylene and polyamide and other fibers are effectively sized with the size compositions of the invention. The polyester consists of a branched chain phosphorus- containing polymer which is the reaction product of at least one dicarboxylic reactant, at least one diol or polyoxyalkylene glycol and a phosphorus acid reactant selected from the class consisting of phosphorus pentoxide, phosphoric acid and mixtures thereof.
