Embodiment 1
[0031]
[0032] Put the raw material APPTA-100 (molecular weight: 9500) into the reaction tube, heat it to 190°C under the protection of nitrogen, and carry out the Claisen rearrangement reaction at constant temperature for 10 hours, and then cool the reactant to room temperature to obtain the product CRPPTA-100 (Molecular weight is 9500).
Embodiment 2
[0034]
[0035] The raw material APPTA-50 (molecular weight: 10400) was put into the reaction tube, heated to 190°C under the protection of nitrogen, and the Claisen rearrangement reaction was carried out at constant temperature for 8 hours. Then the reactant was cooled to room temperature to obtain the product CRPPTA-50 (molecular weight 10400).
Embodiment 3
[0037]
[0038] The raw material APPTA-25 (molecular weight: 7600) was put into a reaction tube, heated to 190°C under the protection of nitrogen, and the Claisen rearrangement reaction was carried out at constant temperature for 8 hours. Then the reactant was cooled to room temperature to obtain the product CRPPTA-25 (molecular weight 7600).
