Studies on thermal and flame retardant behaviour of mixtures of bis(m-aminophenyl)methylphosphine oxide based benzoxazine and glycidylether or benzoxazine of Bisphenol A

High performance benzoxazine/CNT nanohybrid network – An easy and scalable way to combine attractive properties

“…This behavior differs from the one observed in literature where LOI increases gradually with the CNT content from 35 to 38 or 31 to 37 for p(Ba-A) or p(MPD-Bz) respectively [28]. In case of p(P-pPDA), the LOI value of the pristine sample is exceptionally high for an halogen-free resin, far greater than the one of improved epoxy resin (20-29) [49][50][51], and in the same range of benzoxazines which already contain CNTs or with additional phosphorous compound [52]. This result is mainly due to the high degree of aromaticity of the P-pPDA structure facilitating the formation of intumescent charred layers as observed in Fig.…”

Characterizations of polybenzoxazine modified with isomeric biphenyltetracarboxylic dianhydrides

“…Moreover, flexural strength and elongation at break of the polybenzoxazine alloys increased with increasing amount of the epoxy resin. Spontón et al [19] developed a mixture of bis(m-aminophenyl)methylphosphine oxidebased benzoxazine (Bz-BAMPO) and glycidylether (DGEBA). The authors reported that the Bz-BAMPO: DGEBA at 2:1 mole ratio showed degradation temperature (T d ) at 5% weight loss of about 347°C compared to 333°C of Bz-BAMPO.…”

Development of a DOPO-containing benzoxazine and its high-performance flame retardant copolybenzoxazines

“…One is copolymerising with epoxy resins [17][18][19] or copolymerising two or more than two benzoxazine monomers. In previous work, we described the synthesis of phosphorus-containing polybenzoxazines from mixtures of bis(m-aminophenyl)methylphosphine oxide based benzoxazine and benzoxazine of bisphenol A [20].…”
