| description | The invention provides a polyester diol and a preparation method thereof. The polyester diol provided by the present invention is an amorphous 1,4-cyclohexanedicarboxylic acid-based polyester diol with a controllable molecular weight. The polyester diol is prepared by polycondensation reaction of 1,4-cyclohexanedicarboxylic acid and ethylene glycol, and the cis content of the 1, 4-cyclohexanedicarboxylic acid is regulated, so that the amorphous product is more easily obtained. The polyester diol provides a new approach for preparing of elastomeric materials with taking elasticity and strengthinto account, the preparation method of the polyester diol is simple, easy to implement and control, has the advantages of high production efficiency, simple equipment, and cheap and rich raw materials, and the polyester diol can be widely used in chemical, mechanical and other related fields, and has important application value and good development prospects.
