Use of renewable resource vanillin for the preparation of benzoxazine resin and reactive monomeric surfactant containing oxazine ring
TL;DR: In this article, vanillin was used to synthesize polybenzoxazine with the expected desirable benzoxazine properties as well as a high char yield of 55.3%.
Journal ArticleDOI
Mechanistic Pathways for the Polymerization of Methylol-Functional Benzoxazine Monomers
TL;DR: In this paper, a series of methylol-functional benzoxazine monomers were synthesized via a condensation reaction of ortho-, meta-, or para-methylol-phenol, aniline, and paraformaldehyde.

Biobased Chitosan/Polybenzoxazine Cross-Linked Films: Preparation in Aqueous Media and Synergistic Improvements in Thermal and Mechanical Properties
TL;DR: The mechanical and thermal properties of cross-linked CTS/MCBP(BA-tepa) films showed unusual levels of synergism, and the tensile strength and thermal stability were significantly enhanced in a nonlinear fashion.
Journal ArticleDOI
Outstanding dielectric and thermal properties of main chain-type poly(benzoxazine-co-imide-co-siloxane)-based cross-linked networks
TL;DR: In this article, a facile approach was used to synthesize poly(benzoxazine-co-imide,co-siloxane) (oHPNI-oda-PDMS), a new main chain-type copolymer featuring benzoxazine, imide, and siloxane units as repeating units.
