The invention provides new aliphatic diester-di-acid-containing PEA polymer compositions with significant improvement in hydrolytic degradation rates as compared to aliphatic di-acid-containing PEA polymers. The di-acids used in the invention PEA compositions include non-toxic fatty aliphatic homologs. These molecules inherently contain two-ester groups, which easily can be cleaved by biotic (enzymatic) and abiotic hydrolysis. Additional di-acid-type compounds useful for active polycondensation are &#x3b1;,&#x3c9;-alkylene dicarboxylates composed of short aliphatic non toxic diols and di-acids. In addition, the invention PEA polymer compositions optionally can include a second monomer, such as a C-protected L-lysine-based monomer, to introduce additional chain flexibility into the polymer. The invention PEA polymer compositions are useful for delivery of bioactive agents when administered internally.
