BIODEGRADABLE POLYESTER CAPABLE OF SPINNING PROPERTY HAVING SUPERIOR PHYSICAL PROPERTIES AND HIGH MELTING POINT, A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: Biodegradable polyester is provided to improve radiation and elongation due to the change of the composition of inserted material, and the control of molecular weight by using aliphatic acid and aromatic acid.;CONSTITUTION: Biodegradable polyester is manufactured by the esterification and the polymerization of diol components, and acid components consisting of aliphatic acid and aromatic acid. The aliphatic acid is one or more mixtures selected from oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, citric acid, pimeric acid, azelaic acid, sebasic acid, nonanoic acid, decanoic acid, dodecanoic acid, and hexadecanoic acid. The diol component comprises a first diol component selected from ethylene glycol, 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, and 1,6- hexanediol, and a second diol component selected from diethylene glycol, and 1,6-hexnaediol.;COPYRIGHT KIPO 2012
