A polymer extender composition comprising monomers copolymerized in the following percentages by weight:

Polymeric extenders for surface effects

A method of treating a fabric or fabric blend to impart soil release properties is disclosed comprising application to the surface of the fabric or fabric blend of a copolymer composition comprising three monomers copolymerized in certain weight percentages wherein the hydrophilic and oleophobic properties of the treated fabric or fabric blend are varied by varying the relative amounts of the monomers employed.

Polymeric compositions for soil release on fabrics

Highly durable oil/water repellents for textiles

A composition providing stain resistance to stone, masonry and other surfaces is provided comprising a mixture of a fluoroalkyl phosphate and a fluoroacrylate polymer.

Stain resistant compositions

This invention relates to a composition and process for preparing an aqueous emulsion composition of a fluorochemical copolymer for imparting oil and water repellency to textiles, the copolymer comprising perfluoroalkyl acrylates or (meth)acrylates; vinylidene chloride; and alkyl acrylates or (meth)acrylates; wherein the resulting emulsion has improved stability under conditions of high alkalinity, a highly anionic environment or high shear.
