Abstract

An aqueous composition including: a) an aqueous medium; b) a polymer; c) from 0.03% to 1% by weight based on the weight of said polymer of a compound having the formula A-B-C-D wherein A is a perfluoro group of the formula CF₃(CF₂)_n wherein n is from 1 to 5, B is a hydrocarbon group of the formula (CH₂)_m wherein m is from 1 to 4, C is a phosphate residue, and D is a cation, wherein said compound has a bioconcentration factor (BCF) from 1 to 1000 is provided. Processes for forming the aqueous composition and a polymeric coating are also provided.
