Diesters of glycolic acid are effective yarn lubricants for use in the textile industry. These compounds also inhibit the growth of bacteria and fungi.

Fatty glycolic acid derivatives as yarn lubricants and as antimicrobial

Derivatives of dicarboxylic acids containing a phosphono group in the alpha and alpha prime position have been made. These have a wide variety of uses as intermediates. Specifically, one of the new compounds is useful in imparting wrinkle resistance as well as flame retardance to cellulosic textiles.

.alpha.,.alpha.'-Bis-(phosphono)dicarboxylic acid derivatives

Perfluoroalkyl iodide monomer and telomer ester adducts of diethyl vinylphosphonate were prepared by free radical addition. Iodine of these adducts was replaced by hydrogen, and derivatives of the reduced phosphonate adducts were prepared, which include phosphonic acids, acid chlorides, and aziridinyl phosphine oxides. The aziridinyl phosphine oxides are used to impart oil and water repellency to cellulosic textiles. The other derivatives are useful as chemical intermediates as well as potential foaming agents.
