摘要:
The present disclosure relates to a degradable material comprising (a) from about 60 weight percent to about 97 weight percent of a first material based on the total weight of the degradable material, and (b) from about 3 weight percent to about 40 weight percent of a second material based on the total weight of the degradable material, where the second material is an oligomer comprising lactate and giycolate. In another aspect, the present disclosure provides a degradable material comprising (a) poly lactic acid, and (b) an oligomer comprising lactate and giycolate, wherein the degradable material has a Tg less than 56° C. In still another aspect, the present disclosure provides a degradable material comprising (a) poly lactic acid, and (b) an oligomer comprising lactate and giycolate, wherein the degradable material has a tan delta peak of less than 65° C. It has been surprisingly found that the degradable materials according to the present disclosure provide physical properties that are not inherent to poly lactic acid alone. It has also been surprisingly found that the degradable materials disclosed herein provide improvements with respect to the processability, production costs, flexibility and ductility without decreasing their degradability.
