BIODEGRADABLE POLYESTER URETHANES, METHOD FOR THE PRODUCTION AND USE THEREOF |
摘要 |
<p>The invention relates to 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. 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 invention also relates to a method for producing the inventive polyester urethanes and to the use thereof as films, rubber bodies, containers, packaging materials and in galenical preparations, as adhesives, adhesive strips and the like. The invention also relates to polymer blends containing the inventive polyurethanes.</p> |
