FAST-HYDROLYZING POLYLACTIDE RESIN COMPOSITIONS

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 tempera...

Zusammenfassung:	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. La présente invention concerne des compositions de résine de polylactide, qui présentent des vitesses d'hydrolyse rapides et laissent de faibles quantités de résidus, qui comprennent un poly(méso-lactide) et un second polylactide. Les compositions de résine de polylactide sont utiles dans des applications dans lesquelles une hydrolyse rapide est souhaitée à des températures légèrement à modérément élevées, telles que dans certaines applications de traitement de puits de pétrole et de gaz.
