Abstract: A polyethylene terephthalate composition which contains an alkali metal phosphate compound in an amount of 1.0 to 3.0 mol/ton inclusive in terms of alkali metal element content, contains phosphorus element in an amount of 1.5 to 5.0 mol/ton inclusive, contains white foreign matters containing phosphorus element and an alkali metal element and having a size of 50 ?m or more in an amount of 1 ppm by volume or Jess, has an inherent viscosity of 0.65 dl/g or more and less than 0.90 dl/g, has a cyclic trimer content of 0.6 wt% or Jess, contains a carboxylic acid terminal group in an amount of 15 eq/ton or Jess, and has an increased amount of the carboxylic acid terminal group (?COOH) of 30 eq/ton or Jess when the composition is subjected to a wet heat treatment (at 155?C, under a 100% RH atmosphere, for 4 hours). Provided are: a polyethylene terephthalate composition which has excellent hydrolysis resistance and is suitable for a front sheet for a solar cell; and a method for producing the polyethylene terephthalate composition.

Abstract: A polyester resin composition which exhibits a reduced amount of production of the acid component monomer and/or oligomers of the polyester is provided. In other words, the object of the present invention is achieved by the following means. (1) A polyester resin composition, wherein the surface roughness Ra of a capture plate is less than 0.150 ?m, as measured when a sample of the polyester resin composition is melt at 300?C for 60 minutes under a nitrogen atmosphere, quickly cooled and thermally treated at 220?C for 8 hours to form scattered products which are then attached to the capture plate. (2) A polyester resin composition, wherein the production rate of an acid component monomer and/or the production rate of oligomers is/are less than 0.70, as defined by the following formulas ( I) and (II): Production rate of acid component monomer = (amount of produced acid component monomer)/(acid component monomer content) (I) Production rate of oligomers = (amount of produced oligomers)/(oligomer content) (II). (3) A method for producing a polyester resin composition, wherein an ionic liquid is added. [Selected Drawing] None

Abstract: Provided is a polyester resin composition in which the amount of acid-component monomer and/or oligomer produced in the polyester is reduced. That is to say, the purpose of the present invention is achieved by the following means: (1) a polyester resin composition characterized in that, after rapidly cooling a sample that has been melted in a nitrogen atmosphere at 300oC for 60 minutes, the surface roughness Ra of a collecting plate to which scattered matter has attached during 8 hours of heat treatment at 220oC is less than 0.150 mm; (2) a polyester resin composition characterized in that the acid-component monomer production rate and/or the oligomer production rate defined by formulas (I) and (II) below is less than 0.70; and (3) a method of producing a polyester resin composition characterized by adding an ionic liquid. Formula (I): acid-component monomer production rate = (amount of acid-component monomer produced)/(acid-component monomer content) Formula (II): oligomer production rate = (amount of oligomer produced)/(oligomer content)
