A high-performance matrix is the key base for the fabrication of high-frequency copper-clad laminates. A high-performance resin system based on commercial poly(phenylene oxide) (PPO) and 2,2 0 -bis(4-cyanatophenyl) isopropylidene (BADCy), coded as PPO-n/ BADCy (where n is the weight parts of PPO per 100 weight parts of BADCy), was developed. The effect of PPO on the key properties, including the dielectric and thermal properties, water resistance, and toughness, of the cured resins was investigated extensively. The results show that PPO not only catalyzed the curing reaction of BADCy but also reacted with BADCy to form a singlephase structure. Furthermore, compared with the cured BADCy resin with 1 phr epoxy resin as a catalyst, the cured PPO-n/BADCy resins had significantly increased impact strengths and decreased dielectric constants, loss, and water resistance. The reasons behind these desirable improvements are discussed from the view of structureproperty relationships. These results suggest that the PPO-n/BADCy system has great potential to be used as a matrix for high-frequency copper-clad laminates or other advanced composites.

“…The gel time of the resins was measured by the plate small knife method in the air atmosphere. 24 The short beam shear test was performed on a universal testing machine (AG-X10KNSTD, Shimadzu, Japan) in ASTM (American Society for Testing Material) standard D2344. Standard interlaminar shear strength (ILSS) specimens of 30 mm in length, 6 mm in width, and 2 mm in thickness were used in the study.…”

ABSTRACT:The effects of novolac resin (NR) and modified novolac resin (MNR) on the stiffness and toughness of the carbon fiber (CF)/epoxy composites were studied when using these two kinds of modifiers with different physical and chemical performance. The results show that both NR and MNR are excellent toughening agents for the CF/epoxy composites, and the composites treated with MNR present better toughness than that of NR. However, the stiffness of the composites is almost unchanged when adding MNR. The mechanisms were analyzed by fracture studies using scanning electron microscopy and the decrease of cross-link density caused by MNR was deduced to the toughening effects. C

Dynamic mechanical analysis was conducted on specimens prepared from cyanate ester (CE) and epoxy (EP) resins cured together at various mass compositions. Increase of amount of epoxy resin in composition was shown to have a disadvantageous effect on glass transition temperature (T g ). It was shown that post-curing procedure was needed to produce a polymer matrix with a single glass transition relaxation, but increase in post-cure temperature up to 250°C resulted in slight reduction in T g for epoxy/ cyanate copolymers. TG results proved that the presence of epoxy resin reduces thermal stability of the cyanate/epoxy materials. The neat CE and EP/CE systems containing 30 wt% of epoxy resin were modified using epoxy-terminated butadiene-acrylonitrile rubber (ETBN) and polysiloxane core-shell elastomer (PS). The scanning electron microscopy (SEM) results showed the existence of second phase of ETBN and PS modifiers. Only in the case of EP/ CE composition modified with ETBN, well-dispersed second phase domains were observed. Analysis of SEM images for other CE-and EP/CE-modified systems revealed the formation of spherical aggregates.
