“…Many methods have been employed to overcome the inherent brittleness of bismaleimide resins. These include the linear chain extension reaction of the constituents prior to crosslinking with aromatic diamines via Michael addition reaction [2], the incorporation of engineering thermo-plastics such as polyimide, polyether-ketone or polyethersulfone, polyhydantoin etc. [3][4][5] or natural rubber [6].…”

New poly(1,2,3-triazole)s functionalized with allyl groups were prepared by the 1,3-cycloaddition reaction (click reaction) of azido-imides to bispropargyl monomers containing allyl groups. The copolymers of 4,4'-bismaleimidodiphenylmethane with allylated polytriazoles were prepared and their properties investigated. Modified bismaleimide resins had excellent processing compared with neat bismaleimides, especially improved olubility and faster thermal polymerization rate. In addition, the new cured systems had good thermal and dielectric properties (dielectric constant at 1 kHz ranged between 3.09 and 3.39, except the polymer with aliphatic segment instead of the imide group that had a higher constant, namely 4.6).

“…The most popular thermosetting bismaleimide resin systems are combination of 4,4 0 -bismaleimidodiphenylmethane (BMI) and 2,2 0 -diallylbisphenol A 20,21 or 4,4 0 -diaminodiphenylmethane (DDM). 22,23 As a convenient method introducing MHB interaction to the BMI-curing system, the utilization of ML and diallyl isocyanurate (DAIC) is considered (Figure 1). ML and DAIC can undergo MHB as is shown in Figure 2, in a similar manner to melamine cyanurate analogs.…”

Prepolymerizations of 4,4 0 -bismaleimidodiphenylmethane (BMI), diallyl isocyanurate (DAIC), and melamine (ML) at 160-1708C and subsequent compression molding at 200-2808C yielded cured BMI/DAIC/ML resins with feed molar ratios of 4/1/1, 3/1/1, and 2/1/1 (BMI-DAIC-ML411, 311, and 211). Similarly, cured BMI/DAIC 1/1 and BMI/ML 3/1 resins (BMI-DAIC11 and BMI-ML31) were prepared. The FT-IR analysis revealed that the maleimide and allyl groups were almost consumed for all the cured resins, and the hydrogen bonding interaction became stronger with decreasing BMI contents for BMI-DAIC-MLs. Based on the cured structures elucidated from the FT-IR result, the numbers of multiple hydrogen bonds and cross-linking covalent bonds (N MHB and N CB ), and total cross-linking bond energy (E TB ) were evaluated to be 0, 7.92, and 618 for BMI-DAIC-ML411, 0.71, 7.81, and 627 for BMI-DAIC-ML311, and 0.95 mol kg 21, 7.61 mol kg 21, and 617 kcal kg 21 for BMI-DAIC-ML211, respectively. A higher order of glass transition and 5% weight loss temperatures for BMI-DAIC-MLs was 411 > 311 > 211 in accordance with a higher order of N CB . BMI-DAIC-MLs displayed a weak tan d peak at 70-1508C due to dissociation of the hydrogen bonds. The flexural strength and modulus of BMI-DAIC-ML311 were higher than those of BMI-DAIC-ML411 in accordance with the difference of E TB . V C 2015 Wiley Periodicals, Inc. J. Appl.

“…[1] However, because of its rigid and symmetrical structure, the common BMI monomers generally possess poor solubility in common organic solvents and higher melting temperature; the cured resins have high inherent brittleness due to their high cross-link density and rigid molecular networks. These shortcomings have considerably restricted their applications.…”

Two novel bismaleimide (BMI) monomers containing fluorene cardo group and aryl ether linkage, that is, 9,9-bis [4-(4-maleimidophenoxy)phenyl] fluorene (PF-BMI) and 9,9-bis[4-(4-maleimidophenoxy)-3-methylphenyl] fluorene (MPF-BMI) based on 9,9-bis(4-hydroxyphenyl)fluorene and its derivative were designed and synthesized. The chemical structures of the monomers were confirmed from 1 H NMR, 13 C NMR spectroscopy, and Fourier transform infrared spectroscopy. Both monomers obtained are readily soluble in common organic solvents, such as acetone, dichloromethane, and chloroform, enabling an easy solution processing. The thermal curing behavior of the monomers and their non-isothermal thermal curing processes were investigated using differential scanning calorimetry, displaying that both monomers have lower melt points and broad thermal processing windows. The corresponding kinetic data, for example, activation energy (E a ), pre-exponential factor (A), and the order of the reaction (n), were obtained by the Kissinger and Ozawa method. The BMI resins based on these new monomers have good thermal stability seen from the thermogravimetric analysis results.
