Polycondensation catalyst for producing polyester and method for producing polyester using the same |
| abstract |
According to the present invention, there is provided a polycondensation catalyst for producing a polyester polycondensation catalyst obtained by esterification or transesterification of a dicarboxylic acid or an ester-forming derivative thereof with a glycol, which comprises 100 parts by weight of the solid base, and having an inner coating layer containing titanic acid in an amount of 0.1 to 50 parts by weight in terms of TiO 2 on the surface of the particles of the solid base, and having 1 to 50 parts by weight of aluminum on the surface of the inner coating layer. An oxide of at least one element selected from zirconium and hafnium or a composite oxide of at least two elements selected from aluminum, zirconium and hafnium to form a solid base particle of the outer side coating layer. |
