Abstract

PURPOSE: To obtain specified characteristics of the dialytic membrane used for artificial kidney with steam sterilization, by the thermal processing of the membrane formed with chitosan and chitin in the warm water.
CONSTITUTION: Warm water processing (e.g. in the state of constant length at ≥60°C, or under limited contraction) is applied to the membrane obtained by the known method from chitosan, chitin or acetylated chitin of 0W20 degree of the acetyl substitution. In this dialytic membrane, the rate of decrease of the dialytic coefficient for water or a solute ≤10,000MW is ≤15% when steam sterilization is performed at 80W140°C.
