Polyurethane-based compositions for the preparation of bio-degradable materials by calandering

摘要

Such compositions comprise in addition to the polyurethane resin which is the essential component, a carbohydrate, at least one second thermoplastic polymer miscible in the molten state with the polyurethane and / or at least one third biodegradable polymer chosen from aliphatic polyesters biodegradable, preferably of the same nature as the base polyester polyurethane implemented.
