Polylactide resin compositions that exhibit rapid hydrolysis rates and leave small amounts of residuals include a poly(meso-lactide) and a second polylactide. The polylactide resin compositions are useful in applications in which rapid hydrolysis is wanted under mildly to moderately elevated temperatures, such as in certain oil & gas well treatment applications.
