hydrofil biopolymer copolyelektrolyt and its application, in particular in biodegradable sarforbindinger

摘要

Hydrophilic biopolymeric copolyelectrolytes are prepared from (a) a water-soluble linear anionic protein polyelectrolyte component derived from keratin, such as ammonium keratinate, and (b) a water-soluble linear cationic biopolymer polyelectrolyte component derived from a glucosaminoglycan and/or collagen, such as chitosan acetate and/or collagen acetate. Hydrogel membranes formed from the copolyelectrolytes are useful as biodegradable dressings for burn wounds and other denuded tissue wound sites.
