Abstract

A gas permeable material having pores through it, in which the pore interiors are coated with the reaction product of a) an ester of a perfluoroalkyl alcohol and a poly-basic hydroxyl-carboxylic acid, and b) a melamine formsldehyde, urea-formaldehyde, or glycol modified formaldehyde. The material is oleophobic and is useful in filtration applictions and in garments.
