Exploration of Poorly Recognized Advantages of Supply Chain Sustainable, Various Aliphatic Multiamine-Based Polybenzoxazines.

ABSTRACT: Aliphatic amine-based viscous benzoxazine resins that are liquid at or near room temperature have great potential for their ease of processability and raw material accessibility, which will play a significant role in large-scale industrial applications. In this study, eight aliphatic benzoxazines are synthesized by the traditional Mannich reaction under solventless conditions using linear diamines, branched diamines, or triamine and cycloaliphatic diamines with eugenol and paraformaldehyde. A recycling sample preparative size-exclusion chromatography (SEC) is used to obtain the purified products. ¹H and ¹³C nuclear magnetic resonance (NMR) spectroscopy and Fourier transform infrared (FTIR) spectroscopy are employed to study the molecular structure of all the aliphatic
