The biodegradability of poly( d-valerolactone-co-L-lactide)s was studied both with enzymatic (lipase from Rhizopus arrhizus ) and nonenzymatic hydrolyses. The hydrolyzability was evaluated by recording the amount of the hydrolyzed watersoluble products. The enzymatic hydrolysis was considerably affe

## Abstract Methyl esters of microbial poly(__β__,L‐malic acid) for conversion degrees of 25, 50, 75, and 100% were prepared by treatment of the polyacid with diazomethane. Esterification proceeded with retention of the molecular weight of the parent polyacid and the copolymers displayed a blocky m
