Abstract: The present invention relates to a copolymer polyester resin and a molded product using the same, and more specifically to a copolymer polyester resin that contains 10˜80 mol % of 1,4-cyclohexane dimethanol, 0.1˜50 mol % of a diol compound expressed as HO—(CH2)n—CO—(CH2)b—OH (where a and b are integers in the range 1˜5), and ethylene glycol or other diols so that the sum of its entire diol composition is 100 mol % based on dicarboxylic acid. The copolymer polyester resin of the present invention enables reduction of cycle time, improvement of product processability and prevention of PET bottle deformation during mold processing with a heat-shrinking label by complementing low temperature shrinkage, maintaining a high shrinkage rate, and reducing shrinkage stress.

Abstract: The present invention relates to a copolymer polyester resin and a molded product using the same and more specifically to a copolymer polyester resin that contains 10˜80 mol % of 1,4-cyclohexane dimethanol, 0.1˜30 mol % of a cyclohexane dimethanol compound expressed as HOH2C—[C6H12]m—[C6H12]—CH2OH (where m is an integer from 1˜10), and ethylene glycol as the remainder so that the sum of the entire diol composition may be 100 mol % based on an aromatic dicarboxylic acid. The copolymer polyester of the present invention enables superior products to be provided that reduce cycle time and enhance product processability during mold processing using a heat-shrinking label by complementing low temperature shrinkage properties that may be exhibited by the polyester resin of the prior art copolymerized with 1,4-cyclohexane dimethanol.
