  • Publication number: 20130267674
    Abstract: The present invention provides a polyester resin obtained by using an aluminum compound and a phosphorus compound as a polymerization catalyst, containing greater than or equal to 85% by mol of an ethylene terephthalate structural unit, wherein the content of an aluminum-based contaminant with respect to the mass of the polyester resin is less than or equal to 100 ppb, and the content of a phosphorus compound represented by a specific structure is 5 to 11 ppm. The present invention is able to provide a polyester resin capable of keeping high transparency of the molded body when it is sequentially polymerized and produced on a commercial scale, and having such characteristics that crystallization of a mouth plug part can be easily controlled when it is used for a heat resistant bottle, and whitening is less likely to occur at the time of heating in molding when it is used as a sheet for molding.
