Synthesis, characterization, and thermally activated polymerization behavior of bisphenol-S/aniline based benzoxazine

Monofunctional benzoxazine from cardanol for bio-composite applications

“…Other aromatic stretching bands were observed at 1621, 1600 and 1578 cm À1 . CAH stretching vibrations of benzene ring appeared at 3016 cm À1 and the peaks at 2927 and 2854 cm À1 are owing to the asymmetric and symmetric stretching vibrations of CH 2 of oxazine ring as well as alkyl side chain of cardanol [13,14].…”

Polyether‐based main‐chain‐type polytriazole elastomer with benzoxazine via a 1,3‐dipolar cycloaddition reaction

“…[6][7][8][9][10] However, applications in the synthesis of elastomers with benzoxazine structures have rarely been reported. After the fundamental investigation of benzoxazine chemistry was done by Burke and coworkers, 2-4 benzoxazine resin was proven to be a novel functional material with high performance.…”

Synthesis and Characterization of Substituted Bisbenzoxazine as Potent Antimicrobial Agent

“…These benzoxazines were synthesized from monophenols, monoamines, and formaldehyde, but they could not form polymers with high molecular weight. After benzoxazines based on bisphenol-A were synthesized [5,6], a series of bifunctional benzoxazines have been prepared from bisphenols (or monophenols), monoamines (or diamines), and formaldehyde [7][8][9][10][11][12][13][14][15]. The bifunctional benzoxazines can form into polybenzoxazines with high molecular weight via thermally activated ring-opening polymerization reaction [16][17][18][19], and the resultant polybenzoxazines possess excellent properties, such as relatively high glass transition temperature, superior mechanical properties, excellent electrical insulation properties, low moisture absorption, high thermal stability, high char yields, and low flammability.…”
