<p>PURPOSE: A catalyst compound for manufacturing polyester resin, homopolyester or copolyester resin manufactured by the same, and a shaping container are provided to improve the yellowing phenomenon of polyester resin by containing the optical contents of titanium, a complexing agent, and metal salt. CONSTITUTION: A catalyst compound for manufacturing polyester resin includes a titanium alkoxide-based solution or a titanium compound represented by structural formula I. In structural formula I, the R is respectively alkyl radical, cycloalkyl radical, aralkyl radical, or the combination of the same; and each R contains 1 to 30 carbon atoms per radical. The catalyst compound further includes a complexing agent and/or metal salt. The metal of the metal salt is one or more from aluminum, manganese, iron, cobalt, zinc, gallium, and germanium. The complexing agent is one of hydroxyl carboxylic acid, alkanolamine, and aminocarboxylic acid.</p> |
