摘要： Disclosed are a copolymeric polyester resin composition having outstanding color stability (transparency) and a production method therefor. The copolymeric polyester resin composition comprises: between 95 and 99.99 percent by weight of a copolymeric polyester resin having a structure which is obtained by the copolymerization of a dicarboxylic acid component and a diol component that comprises isosorbide, and in which there is repetition of a dicarboxylic acid moiety derived from the dicarboxylic acid component and a diol moiety derived from the diol component; and between 0.01 and 5 percent by weight of an antioxidant selected from the group consisting of hindered phenol-based antioxidants, phosphite-based antioxidants, thioether-based antioxidants and mixtures thereof.

摘要： Disclosed is a method for preparing a polyester resin, wherein phosphate additives are used in preparing polyester resin to improve the reactive property of the esterification reaction or transesterification, as well as the flame retardancy property and the color stability of a polyester resin. The method for preparing a polyester resin comprises the steps of: carrying out an esterification reaction and/or an ester exchange reaction of a diacid component and a diol component in a presence of phosphoric acid derivatives, wherein the diol component comprises a primary diol and isosorbide, and wherein a reaction time of the esterification reaction or the ester exchange reaction is reduced and the remaining rate of isosorbide in the main chain of the polyester resin is increased.
