POLYESTER RESIN COMPOSITION FOR FILM CONTAINING TITANIUM-BASED CATALYST AND PREPARATION METHOD THEREFOR
The present invention enables a polycondensation reaction of polyester at a low temperature to lead to an improvement in thermal stability as well as a high degree of polymerization in a polyester resin, so that a polyester resin with a minimized end group (carboxyl group) and a small content of foreign matter can be produced. In addition, when a film is manufactured using the polyester resin, a film with a uniform thickness can be produced because no gap is formed between the drum surface and a sheet-like product even at a high rotational speed due to an excellent electrostatic application property and a small melt specific resistance of the polyester resin, and a film with high transparency can be produced due to a small content of foreign matter.
