Abstract
Permselective membranes are provided consisting of lactam-polyol-polyacyl lactam block terpolymers having from 35 to 75% by weight polylactam blocks and 25 to 65% by weight polyalkylene ether blocks. The membranes are particularly suitable as blood dialysis membranes having improved permeability to solutes in the medium range of molecular weights while maintaining acceptable ultrafiltration rates and permeability to low molecular weight solutes. The membranes are provided both as planar films and hollow fibers, have high hydrolytic stability under hot wet sterilization conditions and good mechanical properties under hemodialysis conditions.
