“…The cured cyanate ester resins exhibit good mechanical properties, superior dielectric properties, excellent adhesive properties and good moisture resistance, etc. [1,2]. These unique properties of cyanate resins make them excellent candidates for many cutting-edge applications such as high-frequency numeric printed circuit board, aerospace structures, adhesives and functional materials [3][4][5].…”

In this article, a hybrid filler based on polyhedral oligomeric silsesquioxane and silica, coded as POSS-SiO 2 , has been successfully synthesized. The structure of POSS-SiO 2 was studied by Fourier-transform infrared spectra, X-ray diffraction, and scanning electron microscopy. Then the POSS-SiO 2 was compounded with dicyclopentadiene bisphenol dicyanate ester (DCPDCE) resin to prepare composites. The effects of POSS-SiO 2 on the curing reaction, mechanical, thermal, dielectric and tribological properties of DCPDCE resin were investigated systematically. Results of differential scanning calorimetry show that the addition of POSS-SiO 2 can facilitate the curing reaction of DCPDCE and decrease the curing temperature of DCPDCE. Compared with pure DCPDCE resin, the impact and flexural strengths of the composites materials are improved markedly with up to 72 and 52% increasing magnitude, respectively. Meanwhile, the POSS-SiO 2 /DCPDCE systems exhibit lower dielectric constant and loss than pure DCPDCE resin over the testing frequency

“…However, the T g , thermal stability, and dielectric properties were compromised with the addition of epoxy. Bismaleimide-triazine resin (BT resin), comprising a blend of BMI and CE resins, enjoyed the advantages of the two resin systems, possessing a combination of good processability, high T g , low relative permittivity and loss, as well as reduced moisture absorption [17,18]. However, the toughness of BT resin remained at a low level because of the inherent brittleness of BMI.…”

Abstract. Highly soluble fluorinated ethynyl-terminated imide (FETI) oligomers were prepared via a conventional one-step method in m-cresol, using 4, 4′-(hexafluoroisopropylidene) diphthalic anhydride and 2, 2′-bis(trifluoromethyl) benzidine as the monomers, and ethynylphthalic anhydride as the end-capper; then interpenetrating polymer networks (IPN) were formulated from FETI oligomers and bisphenol A dicyanate ester (BADCy) through a solvent-free procedure, and their thermal, mechanical, and dielectric properties were fully characterized. The curing mechanism was studied by model reactions using nitrogen nuclear magnetic resonance. As evidenced by differential scanning calorimetry analysis and rheological measurements, the FETI/BADCy blends exhibited lower curing temperature and shorter gelation time in comparison with pure BADCy due to the catalytic effects of ethynyl and residue amic acid groups. The properties of IPNs were fully compared with those of polycyanurate, and the results revealed that the incorporation of FETI into cyanate ester resins could significantly improve the toughness, glass transition temperatures, mechanical and dielectric properties of the resultant IPNs.

The new bismaleimide monomer N,N'-bis(maleimide)benzenesulfonamide [BMBS], homopolymer N,N'-bis(maleimide)benzenesulfonamide[HBMBS] and copolymers-N,N'-bis(maleimide)benzenesulfonamide-vinyl acetate [CBMBS-A] and N,N'-bis(maleimide)benzene sulfonamide-ethyl vinyl acetate [CBMBS-B] were formed by addition reaction followed by dehydration -cum-cyclization of 4-amino sulfonamide and maleic anhydride. Polymerization process was accompanied by AIBN-THF free radical initiator-solvent selected by trying of many initiatorsolvent system. Melting points were determined by open capillaries method and compounds structures were confirmed from FT-IR spectra (KBr) spectrophotometer. 1 H NMR spectra of all compounds were recorded, using TMS as internal reference. Antifungal activity were examined by various fungus-strain of Candida albicans, Alternaria soloni and Aspergillus niger and results were compared with Griseofulvin as standard reference anti-fungal drug.
