Polyester Resin Compositions, Catalyst for Polyester Production, Polyester Film, and Magnetic Recording Medium |
| abstract |
An object of the present invention is to provide a polyester which can be provided practically without using an antimony compound as a polycondensation catalyst.n n n (I) In the present invention, the content of the antimony element is 30 ppm or less by weight, the titanium element is 0.5-50 ppm by weight, the phosphorus element is 0.1-100 ppm by weight, and the titanium element is equivalent. It is a polyester resin composition whose number density of particle | grains whose circular diameter is 1 micrometer or more is less than 100 /0.02 mg.n n n (II) In the present invention, the content of the antimony element is 30 ppm or less in terms of weight, contains 0.5 to 50 ppm of the titanium element by weight, 0.1 to 100 ppm of the phosphorus element by weight, and is based on the dynamic light scattering method. It is a polyester resin composition containing 0.1-5 weight% of organic polymer particles whose average particle diameter is 0.05-3 micrometers, and the fraction of the number of the coarse particle | grains more than twice the average particle diameter with respect to the total particle number is 0.01% or less. |
