This invention belongs to the field of polymer materials technology and discloses a high-temperature resistant, high-transmittance nylon copolymer, its preparation method, and its applications. Terephthalic acid, isophthalic acid, 1,4-cyclohexanedicarboxylic acid, and hexamethylenediamine are selected as raw materials. The preparation process uses deionized water as a solvent, mixing all raw materials and solvent in a specific ratio and adding them to a reaction vessel. Through copolymerization, a nylon copolymer is formed. This nylon copolymer, due to the introduction of rigid benzene rings and aliphatic six-membered ring structures into the amorphous polymer PA6I macromolecule, maintains high transmittance while increasing the material's heat resistance. This invention sets technical indicators in the copolymerization salt formation process, ensuring controllable copolymer salt quality and minimizing the impact of copolymer salt quality issues on subsequent polymerization. No additional catalysts or antioxidants are required during preparation, reducing production costs. Furthermore, the preparation process does not require maintaining high temperatures and pressures, facilitating industrialization while reducing production costs.

The present disclosure relates to compositions of matter, methods, and systems for analyzing polymeric macromolecules, including polymeric macromolecules such as peptides, polypeptides, and proteins.
