The present invention provides biodegradable polymer particle delivery compositions based on polymers, such as polyester amide (PEA) and polyester urethane (PEUR) polymers, that contain amino acids in the polymer. The polymer particle delivery compositions can be formulated as a liquid dispersion of...http://www.google.es/patents/US20060177416?utm_source=gb-gplus-sharePatente US20060177416 - Polymer particle delivery compositions and methods of use
