  • Patent number: 11518848
    Abstract: A polyester resin that exhibits heat resistance and transparency by including at least dispiro[5.1.5.1]tetradecane-7,14-diol as a diol component, and a preparation method of this polyester resin are disclosed. The polyester resin is obtained by copolymerization of two or more glycols in addition to dispiro[5.1.5.1]tetradecane-7,14-diol and dicarboxylic acid component, which may include terephthalic acid. The diol component may include 1,4-cyclohexanedimethanol in a range from 30 to 50 mol % based on 100 mol % of the dicarboxylic acid and dispiro[5.1.5.1]tetradecane-7,14-diol in a range from 5 to 60 mol % based on 100 mol % of the dicarboxylic acid moiety and ethylene glycol.
