Embodiment 1

[0036] Example 1 Preparation of Biomass-Based Functional Polyamide 1

[0037] The functional polyamide monomer 1 was prepared as follows: 100 g of methyl undecylenate and 1 g of 1,3-diamino-propanol were added to 4 ml of tetrahydrofuran. After passing argon for half an hour, place it in a 40°C oil bath, add 10ml of sodium methoxide, react at 40°C for 20 hours, and then recrystallize to obtain a white powdery solid, which is the hydroxyl amido monomer.

[0038] The 1HNMR spectrum of the functional polyamide monomer 1 is as follows figure 1 As shown, from the e peak at 3.38ppm and the f peak at 3.8 in the figure, it can be seen that the monomer contains amide groups and hydroxyl groups; at 4.85ppm, 5.0ppm and 5.8ppm, the three peaks a, b, and c show single The monomer contains a double bond, proving the successful preparation of functional polyamide monomer 1.

[0039] The structural formula of the functional polyamide monomer 1 is as follows:

[0040] where R 1 It is -OH ...

[0050] Example 2 Preparation of Biomass-Based Functional Polyamide 2

[0051] Biomass-based functional polyamide 2 was prepared as follows: the preparation method was the same as in Example 1, except that 1200 mg of functional polyamide monomer 2 and 300 mg of functional polyamide monomer 1 were added to obtain functional polyamide 2.

Embodiment 3

[0052] Example 3 Preparation of Biomass-Based Functional Polyamide 3

[0053] Biomass-based functional polyamide 3 was prepared as follows: the preparation method was the same as in Example 1, except that functional polyamide monomer 2 was added with a mass of 750 mg and functional polyamide monomer 1 with a weight of 750 mg to obtain functional polyamide 3.

[0054] The H NMR spectrum of functional polyamide 3 is as image 3 shown, compared figure 1 , figure 2 , The peaks at 1.7ppm, 2.3ppm, 3.8ppm and 4.8ppm indicate that the copolymer of Example 3 has functional polyamide monomer 1 and functional polyamide monomer 2 at the same time. It shows that functional polyamide monomer 1 and functional polyamide monomer 2 can be copolymerized into functional polyamide by this method.

[0055] Figure 4 It is the atomic force microscope observation of functional polyamide 3, as can be seen from the figure that functional polyamide 3 contains a large amount of nanoscale crystals, i...

Abstract

The invention relates to an ultra-high strength thermoplastic elastomer and a preparation method thereof. The ultra-high strength thermoplastic elastomer is prepared from functional polyamide; a structural formula of the functional polyamide is shown in the description; the structural formula of the functional polyamide comprises a first repetition structure unit and a second repetition structure unit; when R1 is -OH, the R1 is the first repetition structure unit; when the R1 is a formula shown in the description, the R1 is the second repetition structure unit, wherein n is greater than or equal to 5 and less than or equal to 5000. The elastomer is obtained by carrying out stretching and relaxation circulating mechanical treatment on the functional polyamide. The structure of the selected functional polyamide provides supports for excellent mechanical properties; the functional polyamide is subjected to a plurality of times of circulating stretching mechanical treatment to form the ultra-high strength thermoplastic elastomer; the elastomer can realize ideal mechanical properties; the selected functional polyamide can be synthesized through natural raw materials and provides a beneficial way for creating a sustainable, green and environment-friendly society.

Description

technical field [0001] The invention belongs to the field of biomass-based polymer materials, and in particular relates to an ultra-high-strength thermoplastic elastomer and a preparation method thereof. Background technique [0002] Thermoplastic elastomers are found in every aspect of our lives today, such as adhesives, coatings, tubes, tires and fibers. However, most elastomers today are prepared from non-renewable resources, and renewable biomatrix thermoplastic elastomers are still in their infancy. Scientists have also developed many biomass-based thermoplastic elastomers, such as bio-based polyurethane elastomers (Donglin Tang, ChristopherW.Macosko, Polym.Chem., 2014, 5, 3231-3237), protein-based thermoplastic elastomers (Karthik Nagapudi, William T. Brinkman, Macromolecules, 2005, 38(2), pp345–354), polyester urethane thermoplastic elastomers (Janne and Jukka V. Macromolecules, 1997, 30(10), pp 2876–2882), Biomass-based elastomers derived from fatty acids (Shu W...
