Publication number: 20240084128Abstract: Embodiments relate to a biodegradable and polymerizable polyester composition, to a biodegradable polyester resin prepared therefrom, and to a process for preparing the same. As the biodegradable and polymerizable polyester composition comprises an inorganic filler in a certain content and satisfies a certain range of viscosity, it has excellent dispersibility during polycondensation; thus, it is possible to control the content of metals in a biodegradable polyester resin prepared from the biodegradable polyester polymerization composition and the dispersion index within optimal ranges. In addition, as the biodegradable and polymerizable polyester composition comprising an inorganic filler is subjected to a polycondensation reaction, the dispersibility during the polycondensation reaction is very excellent, which can suppress the aggregation of inorganic filler particles and prevent filter clogging, resulting in a decrease in defects such as voids in the processing process.Type: ApplicationFiled: April 27, 2023Publication date: March 14, 2024Inventors: Kyung Youn KIM, Seong Dong KIM, Hoon KIM, Hyung Mo KIM
