## Abstract An amphiphilic biodegradable polymer, poly(aspartic acidโ__co__โlactic acid) (PAL), was synthesized by simply heating a mixture of aspartic acid (Asp) and Lโlactide without additional catalysts or solvents. The unique branched architecture comprising succinimide units and lactic acid un
Copolymers with a PPG center block and two arms of random glycolide/ lactide copolymers have been synthesized and characterized. Compared to random glycolide/lactide copolymers, these new polymers have high toughness and low elastic modulus. 1 H-NMR spectral lines of glycolide CH 2 protons of the co
