Disclosed are a polymerization catalyst for the production of polyester, which includes an inorganic stannous (tin (II)) compound, and a method of producing polyester using the same. The polymerization catalyst for the production of polyester is safe without toxicity, has equal or higher catalytic activity compared to an antimony-based catalyst, may increase the polymerization reaction rate, may ensure a high viscosity level even when used in small amounts, may reduce the production of acetaldehyde, and may also improve the thermal stability and color of the polymer compared to those of a polyester polymer obtained by the related art. |
