Homogeneous esterification of xylan-rich hemicelluloses with maleic anhydride in ionic liquid.

abstract：:Restorative medicine has a constant need for improved scaffold materials. Degradable biopolymers often suffer from uncontrolled chemical or enzymatic hydrolysis by the host. The need for a second surgery on the other hand is a major drawback for nondegradable scaffold materials. In this paper we report the design and ...
