<P>PROBLEM TO BE SOLVED: To provide a modified polyester resin in which elongation does not significantly decrease even after crystallization, thus allowing extensibility to be maintained and not requiring addition of a large amount of an additive resin or the like, and to provide a polyester resin molded article. <P>SOLUTION: The modified polyester resin is obtained by allowing a polyethylene terephthalate resin to react with one or more polymers selected from the group consisting of a polymer having an amide bond, a polymer having a urethane bond, a polymer having a urea bond, and a polymer having a π bond and a terminal amine in a main chain. The residual elongation percentage represented by the percentage of the elongation after crystallization to the elongation before crystallization of the polyester resin is 50% or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
