AI Technical Summary
Existing technologies do not adequately improve the thermal stability of polyether nitrile, and end-structure control methods have failed to effectively address the problem of decreased thermal stability.
By controlling the end structure of polyether nitrile, ensuring that the integral value of peak A/peak B is below 0.050 in a mixed solvent of pentafluorophenol and deuterated chloroform at a volume ratio of 5:4, and by using appropriate monomer ratios and end-capping agent modification methods, the polymerization reaction time and temperature are controlled to form polyether nitrile under specific conditions.
High thermal stability of polyether nitrile was achieved, reducing weight loss and viscosity increase at high temperatures, and improving the processability and mechanical properties of the material.
