Abstract
Novel microporous fibers and filaments are prepared from normally solid, thermoplastic, orientable, organic polymers which have reactive or reactable groups pendent from the polymer chain, employing a process which involves reactions of said pendent groups while the polymer is in an oriented condition. One of the preferred polymers is a copolymer of ethylene/acrylic acid.
