摘要： Polylactide resin compositions contain certain phosphite esters. The presence of the phosphite ester increases the rate of hydrolysis of the polylactide resin under conditions of moisture (including atmospheric moisture) at mildly elevated temperatures.

摘要： 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.

摘要： Expanded poly(lactide) (PLA) beads are made by pressurizing PLA beads with carbon dioxide at approximately room temperature, heating the beads under pressure to 90 to 160 C to saturate and partially crystallize the beads, and then depressurizing and cooling the beads. The PLA beads contain a blend of PLLA and PDLA in certain ratios. The beads are useful for making expanded bead foam.
