Macromolecular Complexes of Potassium Metaphosphate with Cationic Organic Macromolecules

Abstract

Formation of macromolecular complexes (MCs) of potassium metaphosphate (MPK) with [2-(diethylamino)ethyl]dextran hydrochloride (EA) or glycol chitosan (GC) has been studied. Phase diagrams in three-component system NaBr/acetone/H₂0 were achieved for M Cs prepared from the MPK-EA system at pH 1.0 and MPK-GC system at pH 1.0 to pH 5.0, but were not achieved in the other reaction systems.
The MCs prepared from the, MPK-EA and MPK-GC systems consisted of phosphate and/or metaphosphate with EA and GC, respectively.
