Abstract

PURPOSE: Title material, useful for a dialysis membrane etc., composed of any polycation selected from chitosan, glycolchitosan, glyceridechitosan and N-methylglycolchitosan, and of a polyanion selected from carboxymethylchitins.
CONSTITUTION: A polyion complex, composed of (A) at least one polecation, selected from (a) chitosan, (b) glycol chitosan (c) glyceride chitosan and (d) N- methylglycol chitosan, and of (B) a polyanion selected from carboxymethylchitin and its salt. Where the carboxymethylchitin or its salt has carboxymethylation degree of 0.1W1.0, preferably 0.3W1.0 per N-acetyl-D-glucosamine structural unit. The polyion complex has intrinsic viscosity of 0.1W20 at 20°C.
