“…[32][33][34] It is worth noting that the impact strengths of BP resin are not only higher than that of BD resin, but also comparable to the highest impact strength of halogen-free and phosphorus-free flame retardant bismaleimide resins (13-19 kJ/m 2 ) in SCI database. 11 The good toughness of BP resins can be also confirmed by the morphologies of the fracture surfaces of cured resins. As shown in Figure 7, BP resins have rougher fracture surfaces than BD resin.…”

“…Allyl phenyl compounds are one type of outstanding modifiers for BDM, and 2,2 0 -diallyl bisphenol A (DBA) is the right modifier for BDM resin. 11 However, chemical agents for synthesizing DBA come from petrochemical resources, and the estrogen-like structure of bisphenol A has potential threat such as reducing fertility and increasing the risk of getting diseases including cancers. 12 To solve these problems, it is necessary to develop new ally phenyl compound which is not originated from bisphenol A.…”

High flame retardancy has become a necessary property for heat‐resistant thermosetting resins (HRTRs) in many cutting‐edge fields. However, developing HRTRs with excellent flame retardancy through sustainable strategy (halogen‐free and phosphorus‐free) is still a great challenge. Herein, a novel halogen‐free and phosphorus‐free allyl compound with Schiff base structure (PDM) was efficiently synthesized from biobased protocatechualdehyde, and then four new flame retarding bismaleimide resins (BP1, BP2, BP3, BP4) were developed by building crosslinked network with PDM. The molar ratio of allyl to imide has a significant effect on performances of BP resins, BP2 resin (its molar ratio of allyl to imide is 0.86) shows the best integrated performances, it has not only high impact strength (14.37 ± 1.1 kJ/m2), but also the highest glass transition temperature (343.5°C) and limiting oxygen index (36.4%) among halogen‐free and phosphorus‐free flame retarding bismaleimide resins reported so far. The investigation on flame retardant mechanism of BP resins shows that the mechanism includes condensed‐phase and gas‐phase flame retarding effects.

“…Generally speaking, the bending strength of materials depends on both stiffness and toughness. 28 The behavior is explained in terms of fracture surface morphology. The SEM images of fracture surfaces of VER, VER/PEPABFR and VER/DOPOBFR are shown in Fig.…”

Two PEPA-based (PEPABFR) and DOPO-based (DOPOBFR) flame retardants with vinyl groups were synthesized successfully via 1-oxyphospha-4-hydroxymethyl-2,6,7-trioxabicyclo[2.2.2]octane (PEPA) or 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO) with isocyanoethyl methacrylate using a one-pot method. Their structures were confirmed using Fourier transform infrared, 1 H NMR and 31 P NMR spectroscopies and matrix-assisted laser desorption ionization time-of-flight mass spectrometry. The mechanical performance, thermal properties and flame retardant performance of systems with 15 wt% synthetic flame retardants were investigated using bending tests, differential scanning calorimetry, thermogravimetric analysis, limiting oxygen index (LOI) measurements and cone calorimeter tests. The results show that the bending strength and flexural modulus are improved significantly. The LOI increases to 29.3% and 30.7% with incorporation to 15 wt% PEPABFR and 15% wt % DOPOBFR from the 20.3% corresponding to pure vinyl ester resin (VER). The peak heat release rate decreases by 16.9% and 39.3% and total heat release decreases by 20.1% and 36.4% for VER/PEPABFR and VER/DOPOBFR systems. Furthermore, the flame retardancy mechanism of the flame retardants was studied using thermogravimetric analysis coupled with Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray photoelectron spectroscopy.

“…It has been found that these additives can lead to increases in the flame retardancy and toughness of the thermoset (e.g. an addition of 15 wt% leads to an increase in impact strength from 10.5 to 19 kJ/m 2 and char yield at 800 °C from 27.8 to 53.7 wt%) without impacting the stiffness and Tg too severely [89].…”

Full terms of use are available: http://www.bristol.ac.uk/pure/about/ebr-terms Hamerton, E-mail: ian.hamerton@bristol.ac.uk This review is respectfully and affectionately dedicated to Dr Horst D Stenzenberger, who has been an inspirational figure in modern BMI chemistry, always happy to share his extensive knowledge of this field. ABSTRACT:The chemistry of bismaleimides (BMIs), their blends and copolymers is reviewed critically with particular emphasis placed on the development of the field after 1990, which was marked by several comprehensive review articles. A general introduction to the structure property relationships of BMIs is presented, outlining the development of the preparative chemistry, and the early strategies adopted to address the inherent brittleness of the cured 'first generation' BMI polymers. 'Second generation', diallylbisphenol-toughened BMIs, form the basis of the benchmark commercial systems, and the polymerization mechanism is discussed. The current review is placed in context, addressing the issues of cost, processing and precursor toxicity, the major barriers to wider acceptance of BMIs. The main body of the review evaluates a number of observations made by Dr Horst Stenzenberger in 1990, for the future development of BMI technology. Hence, the synthesis of novel bismaleimide building blocks, incorporation of new thermoplastics and additives, and blending with new thermosetting comonomers are all discussed in detail. The aforementioned review had been written before the concept of nanocomposites or shape memory polymers had been explored with BMIs, but the fields have since grown (especially in the case of the former topic) and are reviewed herein. The application of BMIs to continuous fibre composites is one of the proposed fields of commercial development. The topic falls a little beyond the scope of the present review of BMI chemistry, and is the subject of another publication, but a brief discussion of the most recent developments is presented. The review is concluded with some thoughts about the future outlook for BMI chemistry.
