共聚物聚酯树脂和使用该共聚物聚酯树脂的模塑产品
摘要：
本发明涉及一种共聚物聚酯树脂以及使用该共聚物聚酯树脂的模塑产品，本发明更具体涉及一种共聚物聚酯树脂，其包含10～80摩尔％的1，4-环己烷二甲醇，0.1～50摩尔％的结构式为HO-R6CR7-R4R1R5-COHR2R3(式中R1是碳数为0～10的烷基，R2～R7是氢或者碳数为1～10的烷基)的二醇化合物，以及余量的乙二醇，使得全部二醇组合物的总和为100摩尔％，所述摩尔百分数以芳族二羧酸为基准计。本发明的共聚物聚酯树脂能够在用热收缩标签进行模塑加工的过程中，通过补充低温收缩，保持高收缩率和减小收缩应力，缩短周期时间，改进产品的成型性，防止PET瓶子变形。
摘要（英）：

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-R6CR7-R4R1R5-COHR2R3 (where R1 is an alkyl group with a carbon number of 0-10,and R2-R7 are hydrogens or alkyl groups with a carbon number of 1-10), and ethylene glycol as the remainder so that the sum of the entire diol composition is 100 mol% relative to aromatic dicarboxylic acid. The copolymer polyester resin of the present invention enables reduction of cycle time and 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.
