Title:
POLYETHYLENE TEREPHTHALATE COMPOSITION, ITS MANUFACTURING METHOD, AND POLYETHYLENE TEREPHTHALATE FILM
Document Type and Number:
Japanese Patent JP2005097466
Kind Code:
A
Abstract:
To provide a polyethylene terephthalate composition having excellent hue while using a titanium compound as a polycondensation reaction catalyst, and to provide its manufacturing method and its film.
The polyethylene terephthalate composition and the film comprise a polyethylene terephthalate synthesized with an alkaline earth metal compound and a titanium compound. The amounts of the alkaline earth metal compound and the titanium compound simultaneously satisfy the equations (1)-(3): 10≤M+4Ti≤60 (1); 5≤M/Ti≤30 (2); and 0<Ti≤5 (3) (wherein M and Ti are each a molar concentration (millimole%) of the alkaline earth metal element and the titanium element to the whole dicarboxylic acid component).
