Abstract: A solid crosslinked polyester composition is disclosed wherein the crosslinked polyester is environmentally degradable in less than about 180 days. The crosslinked polyester is the polyesterification reaction product between one or more multi-hydroxylic alcohols, one or more hydroxy acids, and one or more multi-carboxylic acid compounds. Alternately, the crosslinked polyester is the polyesterification reaction product between one or more multi-hydroxylic alcohols, one or more hydroxy acids, one or more multi-carboxylic acid compounds, and a cyclic ester.

Abstract: The present invention provides a polyester which is the reaction product of reactants comprising: (A) an aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms; (B) an aromatic carboxylic acid and/or anhydride; and (C) a polyol. The invention also provides a coating composition comprising the polyester, a method of making the coating composition and the use of at least 2 wt % of a linear aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms as a replacement for at least 2 wt % of an aromatic carboxylic acid and/or anhydride in a polyester composition. This use may improve the UV resistance and/or stability of the polyester composition.

Abstract: A biphasic material and devices comprising the same are provided for the development of conductive conduits that may be used for the treatment of peripheral nerve injury. These devices or conduits are designed such that repeated electric field gradients can be initiated to promote neurite and axonal outgrowth. Conducting conduits using doped synthetic and/or natural polymers create specifically patterned high and low conducting segmented materials, which are mechanically used to produce the electrical properties needed for nerve conduits. These electrical properties stimulate neurite outgrowth and axonal repair following a peripheral nerve transection.
