Embodiment 1
[0035] Embodiment 1: the synthesis of modified polyester resin A
[0036] S1, 83g terephthalic acid, 83g isophthalic acid, 278.6g 2,4:3,5-biscamphor-D-mannitol, 187.5g polyhexamethylene carbonate diol (molecular weight 1000), 92mg Isopropyl titanate is put into the reactor with dropping device;
[0037] S2. Introduce nitrogen to replace the air in the reactor, stir and heat up, and start the reaction at 200°C. At the same time, 37.5g of linear organosilanol (molecular weight 750) is added dropwise, and then the temperature is raised to 240°C-250°C. Finish dripping within 3 hours;
[0038] S3. After the esterification is completed, the polymerization is reduced under reduced pressure at 240°C-270°C, and the reaction is stopped after reaching the end point. Nitrogen gas is introduced to eliminate the vacuum, and the material is extruded.
Embodiment 2
[0039] Embodiment 2: the synthesis of modified polyester resin B
[0040]S1, 133g terephthalic acid, 40g sebacic acid, 239g 2,4:3,5-biscamphor-D-mannitol, 150g polyhexamethylene carbonate diol (molecular weight 500), 102mg iso-titanate Propyl ester is put into the reactor with dripping device;
[0041] S2. Introduce nitrogen to replace the air in the reaction kettle, stir and heat up, and start the reaction at 200°C. At the same time, 75g of linear organosilanol (molecular weight 750) is added dropwise, and then the temperature is raised to 240°C-250°C. Finish dripping within 3 hours;
[0042] S3. After the esterification is completed, the polymerization is reduced under reduced pressure at 240°C-270°C, and the reaction is stopped after reaching the end point. Nitrogen gas is introduced to eliminate the vacuum, and the material is extruded.
Embodiment 3
[0043] Embodiment 3: the synthesis of modified polyester resin C
[0044] S1, 149g isophthalic acid, 20g sebacic acid, 318g 2,4:3,5-biscamphor-D-mannitol, 120g polyhexamethylene carbonate diol (molecular weight 1000), 102mg iso-titanate Propyl ester is put into the reactor with dripping device;
[0045] S2. Introduce nitrogen to replace the air in the reaction kettle, stir and heat up, and start the reaction at 200°C. At the same time, 80g of linear organosilanol (molecular weight: 1000) is added dropwise, and then the temperature is raised to 240°C-250°C. Finish dripping within 3 hours;
[0046] S3. After the esterification is completed, the polymerization is reduced under reduced pressure at 240°C-270°C, and the reaction is stopped after reaching the end point. Nitrogen gas is introduced to eliminate the vacuum, and the material is extruded.
