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&#x2dc;99 mol % of 1,4-cyclohexanedimethanol and (ii) 1&#x2dc;60 mol % of isosorbide with respect to the total diol components.

Polyester resin and method for preparing the same

A copolymerized polyester heat shrinkable film which can be used as a label, a cap seal or a direct packaging for various containers is disclosed. The copolymerized polyester heat shrinkable film is made of a copolymerized polyester resin having alternating structures of acid moieties which are derived from acid components and diol moieties which are derived from diol components, the acid components comprising terephthalic acid, and the diol components comprising isosorbide 1,4-cyclohexanedimethanol and ethylene glycol. The copolymerized polyester heat shrinkable film has a shrinkage initiation temperature of equal to or more than 60&#xb0; C., and a maximum heat shrinkage ratio of less than 2% at 60 to 70&#xb0; C., and a maximum heat shrinkage ratio of 50 to 90% at 90 to 100&#xb0; C.

Copolymerized polyester heat shrinkable film

A blend of polylactic acid resin and copolyester resin and a molded article using the same having superior impact resistance and heat resistance are disclosed. The blend of polylactic acid resin and copolyester resin includes: 5 to 95 weight % of polylactic acid resin; and 5 to 95 weight % of copolyester resin which is a copolymerization product of an acid component including terephthalic acid and a diol component including 5 to 99 mol % of 1,4-cyclohexanedimethanol and 1 to 60 mol % of isosorbide(bio monomer), and has a repeated structure of an acid moiety derived from the acid component and a diol moiety derived from the diol component.
