ABSTRACT:
Disclosed is a viscose membrane suitable for hemodialysis, comprising a viscose membrane substantially equally oriented in the longitudinal and in the transverse directions, having in the dry state a birefringence in each direction of not more than about 6.times.10.sup.-3 and a phase difference of not more than about 150 nm, and wherein during transition from a dry into a wet state, the membrane undergoes a shrinkage of between about 0.5 and 10 percent both in the longitudinal and in the transverse directions. The membrane is produced by a process which is characterized in that the membrane is transversely stretched by 40 to 120% prior to drying.
