Polyethylene Terephthalate Composition Manufacturing Method Therefor And Polyethylene Terephthalate Film
Abstract: Provided is a polyethylene terephthalate composition comprising a copolymer component having at least 3 functional groups in an amount of 0.01 mol% to 1.00 mol% with respect to ethylene terephthalate units in which the ratio (Mw/Mn) between the weight average molecular weight and number average molecular weight of the polyethylene terephthalate composition is 5.0 to 8.0 the polyethylene terephthalate composition also comprising: an alkali metal compound in an amount of 1.0 mol/ton to 3.0 mol/ton in terms of alkali metal element; a phosphorus compound in an amount of 1.5 mol/ton to 5.0 mol/ton in terms of elemental phosphorus; and an o-chlorophenol insoluble matter in an amount of less than 0.5 wt%. The present invention provides a polyethylene terephthalate composition which has excellent hydrolysis resistance and retention of elongation and is suitable for use in a solar cell film.
