COPOLYMER POLYESTER RESIN AND MOLDED PRODUCT USING SAME |
摘要 |
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)a-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% relative to dicarboxylic acid. The copolymer polyester resin of the present invention enables reduction of cycle time, improvement of product moldability 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. |
