## Abstract Poly(anhydride‐esters), based on carboxyphenoxydecanoate (CPD), are biocompatible polymers that hydrolytically degrade. The mechanical properties of the poly(anhydride‐esters) can be altered by copolymerization with __para__‐carboxyphenoxyhexane (__p__CPH). Mechanical properties of thre
## Abstract The hydrolytic degradation of three aromatic poly(ester‐anyhdride)s, PEA's, was studied at 25°C in buffer solutions at pH 6 and pH 7 over a period of 16 and 14 months, respectively. Two PEA's (1 and 2a) possessed an ester/anhydride mole ratio of 75 : 25. The loss of weight, the film thi
