Abstract

The invention relates to a function polyamide monomer, polyamide and preparation methods. A structural formula of the function polyamide monomer is shown in the description, and a structural formula of a side group R1 is -OCOR1' or -OH. A structural formula of the function polyamide is shown in the description, the n is larger than or equal to 5 and smaller than or equal to 5000, and the R2 of a main chain is disulfide. The preparation method of the function polyamide comprises the steps: dissolving the function polyamide monomer, dithiol and a catalyst into a solvent; then introducing protection gas of argon and putting into an oil bath pan to react; finally, obtaining a function polyamide product through methyl alcohol precipitation. According to the invention, a synthetic vegetable oil derivative namely the function polyamide monomer is converted into function polyamide in high efficiency, the final yield of the function polyamide is 50% to 100%, and the purity of the function polyamide is 90% to 100%. The function polyamide disclosed by the invention is synthesized from natural raw materials, has no free formaldehyde, benzene and heavy metal and can meet a national environment-friendly material standard. The function polyamide disclosed by the invention has excellent mechanical capacity and mechanical property.

Description

technical field

[0001] The invention belongs to the field of biomass-based polymer materials, and in particular relates to a functional polyamide monomer, a functional polyamide and a preparation method. 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, Christopher W.Macosko, Polym.Chem., 2014, 5, 3231-3237), protein-based thermoplastic elastomers body (Karthik Nagapudi, William T.Brinkman, Macromolecules, 2005, 38(2), pp 345–354), polyester urethane thermoplastic elastomer (Janne andJukka V. Macromolecules, 1997, 30(10), pp 2876–2882), Biomass-based elastomers derived from fatty acids (S...
