To elucidate the reaction mechanism, we used model compounds to show that benzoxazine homopolymerises and the phenolic hydroxyl groups attack the oxirane rings.…”

Reactive Modification of Thermoplastic and Thermoset Polymers using Flame Retardants: An Overview

“…M.A.Espinosa et al synthesized novolac resins containing benzoxazine rings and cured with isobutyl bis(glycidylpropylether) phosphine oxide (IHPOGly). Their curing and thermal behavior were studied using different epoxy/phenol molar ratios and with or without triphenylphosphine catalyst [89][90][91] .…”

Thermal degradation of polysiloxane and polyetherester containing benzoxazine moieties in the main chain

“…The chemistry of benzoxazine synthesis offers a wide range of molecular design flexibility using appropriate starting materials. Thus, molecular structure can be tailored for specific applications [6][7][8][9][10][11].…”
