Abstract
The processes of the invention enable depositable PFSA to be provided over he entire inner surface of hollow fibers. Additionally, the processes of this invention provide a fiber which is coated by a thin coating of PFSA which is approximately 5-40 .mu.m thick. The fiber can advantageously withstand pressure gradients between 20-75 psig throughout its wall before leakage.
