Abstract
(EN)
This polyhydroxy alkanoate resin composition contains a polyhydroxy alkanoate resin component, wherein the highest melting peak temperature of the resin composition as measured by differential scanning calorimetry is 130°C or higher, and a total crystal melting enthalpy as calculated from all melting peaks is in the range of 20-65 J/g. Preferably, the polyhydroxy alkanoate resin component is a mixture of at least two polyhydroxy alkanoate resins having different crystal melting enthalpies.
(FR)
L'invention concerne une composition de résine de polyhydroxyalcanoate contenant un constituant de résine de polyhydroxyalcanoate, la température du pic de fusion le plus élevé de la composition de résine, telle que mesurée par calorimétrie différentielle à balayage, étant de 130°C ou plus et une enthalpie de fusion cristalline totale, telle que calculée à partir de tous les pics de fusion, étant située dans la plage de 20 à 65 J/g. De préférence, le constituant de résine de polyhydroxyalcanoate est un mélange d'au moins deux résines de polyhydroxyalcanoate présentant différentes enthalpies de fusion cristalline.
(JA)
