| abstract |
The present invention discloses copolymers suitable for use on the surface of a hydrophilically modified porous fluoropolymer support, such as a copolymer of formula (I) or (II):n□ □nWherein Rf, Rh, Ra, Y, m and n are as described herein. Also disclosed is a method of preparing the copolymers, a method of hydrophilically modifying a porous fluoropolymer carrier, a hydrophilic fluoropolymer porous membrane prepared from the polymers, and a method of filtering a fluid through the porous membranes. |
