Synthesis of novel multi-functional fluorene-based benzoxazine resins: Polymerization behaviour, curing kinetics, and thermal properties

In this paper, a new series of novel aromatic multi-functional fluorene-based benzoxazine monomers (AMFB) were synthesized from the reaction of 9,9-bis(4-aminophenyl)-2,7-dihydroxy-fluorene, aniline, paraformaldehyde, and unsubstituted or substituted phen

Synthesis and characterization of cardanol containing tetra-functional fluorene-based benzoxazine resin having two different oxazine ring structures

A new cardanol containing tetra-functional fluorene-based (t-BF-a-c) benzoxazine resins has been successfully synthesized via two-stage Mannich condensation reaction. The monomer contains simultaneous diamine- and bisphenol-type oxazine rings. The FTIR,

Synthesis of novel furan-containing tetrafunctional fluorene-based benzoxazine monomer and its high performance thermoset

A novel furan-containing tetrafunctional fluorene-based benzoxazine monomer with bisphenol- and diamine-type oxazine rings was successfully prepared. The resulting polybenzoxazine exhibits extremely higher glass transition temperature (440 °C) and better
