Embodiment 1
[0037] Preparation of polyester elastomer:
[0038] Raw materials and consumption used in table 1. embodiment 1
[0039]
[0040]
[0041] In a 100ml four-necked bottle, add 1,3-PDO, 1,4-BDO, SuA, SeA, IA according to the amount in Table 1, and put the mixture under N 2 Stir mechanically under atmosphere and heat to 180°C, and keep at 180°C for 2h. Then cool to room temperature, add 0.1wt% tetrabutyl titanate as a catalyst, then gradually increase the temperature to 220°C, pre-condense at -0.06MPa for 1 hour, and then polycondense at -0.1MPa until the product has a climbing effect. Small molecules such as propylene glycol and butanediol produced in the transesterification reaction were distilled under reduced pressure, and finally the product bio-based polyester PPBSIS was obtained.
[0042] Preparation of polyester elastomer modified carbon dioxide-based plastics:
[0043] The bio-based polyester PPBSIS for toughening is obtained from the first step of the synthesis ...
Embodiment 2
[0045] Preparation of polyester elastomer:
[0046] Raw materials and consumption used in table 2. embodiment 2
[0047]
[0048]
[0049] In a 100ml four-necked bottle, add 1,2-PDO, 1,4-BDO, and AA according to the dosage in Table 2. Put the mixture in N 2 Mechanically stirred and heated to 160°C under atmosphere, and kept at 160°C for 2h. Then the temperature was raised to 180°C and kept at 180°C for 2h. Then cool to room temperature, add 0.2wt% tetrabutyl titanate as a catalyst, then gradually increase the temperature to 220°C, pre-condense at -0.06MPa for 1 hour, and then polycondense at -0.1MPa until the product has a climbing effect. Small molecules such as 1,2-propanediol and butanediol produced in the transesterification reaction were distilled under reduced pressure, and finally the product bio-based polyester PPBA was obtained. Since the obtained product is a saturated system rubber without double bonds, the color of the product is relatively light, and the...
Embodiment 3
[0053] Preparation of polyester elastomer:
[0054] Raw materials and consumption used in table 3. embodiment 3
[0055]
[0056] In a 100ml four-necked bottle, add 1,2-PDO, 1,4-BDO, AA, and Gl according to the dosage in Table 3. Put the mixture in N 2 Mechanically stirred and heated to 160°C under atmosphere, and kept at 160°C for 2h. Then the temperature was raised to 180°C and kept at 180°C for 2h. Then cool to room temperature, add 0.2wt% tetrabutyl titanate as a catalyst, then gradually increase the temperature to 220°C, pre-condense at -0.06MPa for 1 hour, and then polycondense at -0.1MPa until the product has a climbing effect. Small molecules such as 1,2-propanediol and butanediol produced in the transesterification reaction were distilled under reduced pressure, and finally the product bio-based polyester PPBAG was obtained. Since the obtained product is a saturated system rubber without double bonds, the color of the product is relatively light, and the color ...
