Versatile post-polymerization modifications of a functional polyester from castor oil

This work reports a series of versatile post-polymerization modifications of an aliphatic functional polyester obtained by enzymatic polycondensation of dimethyl 2,9-dibromosebacate and 1,10-decanediol, both derived from castor oil. The alkyl halide functionality has shown to react with thiols, amines and carboxylic acids under mild conditions obtaining high modification degrees. Moreover, functionalization using NIPAAm-COOH terminated polymer has been carried out. (C) 2015 Elsevier Ltd. All rights reserved.
