Abstract
A polyester resin copolymerized with isosorbide and 1,4-cyclohexane dimethanol and having an improved impact strength, and a method for preparing the same are disclosed. The copolymerized polyester resin has an alternating structure of acid moieties which are derived from acid components and diol moieties which are derived from diol components, wherein the acid components comprise terephthalic acid, and the diol components comprise (i) 5˜99 mol % of 1,4-cyclohexanedimethanol and (ii) 1˜60 mol % of isosorbide with respect to the total diol components.
