BIODEGRADABLE POLYESTER URETHANES, METHOD FOR THE PRODUCTION AND USE THEREOF

摘要

PURPOSE: Provided is biodegradable linear polyester urethanes and to biodegradable cross-linked polyester urethanes obtained from linear polyester urethanes by virtue of the fact that they are cross-linked by diisocyanate bridges. CONSTITUTION: By varying the degree of crosslinking, the physical, chemical and biological properties of the inventive cross-linked polyester urethane can be adjusted and the biodegradability thereof can also be varied considering that biological degradability occurs more slowly as the degree of crosslinking increases. The inventive polyester urethanes is used as films, rubber bodies, container, packaging materials and in galenical preparations, as adhesives, adhesive strips and the like.
