Abstract
Disclosed is a catalyst compound for preparing a polyester resin. Provided are a novel catalyst compound for preparing a polyester resin, a polyester resin prepared using the compound and a container molded using the resin. The polyester resin is nontoxic, is environmentally friendly and exhibits high intrinsic viscosity and superior colors L and b, thus solving reaction speed during solid state polymerization and a yellowing phenomenon, problems associated with use of conventional titanium catalysts.
