“…On the contrary, low viscosity would cause coalescence and rupture of bubbles during the blowing process. Figure 2 shows the steady shear viscosity of CE60 mixture resin system as a function of time, cured at temperature from 140 C to 180 C. It can be observed that the viscosity of the systems shows a similar tendency and possess an induction period 29,30 (where the increase in viscosity is modest and gradual, followed by an extremely rapid exponential increase in viscosity). The induction period in steady shear viscosity is about 53, 35, 22, and 17 min at 140, 150, 170, and 180 C, respectively, as seen in Figure 2.…”

A new type of cyanate (CE)/epoxy (EP) foam with bisphenol-A dicyanate ester prepolymer and diglycidyl ether of bisphenol-A (BADCy/DGEBA) has been successfully prepared through a two-step process. The structure and properties of CE/EP foam were studied. The results reveal that the CE/EP foams, with relatively uniform cell structure, were composed of closed cells as confirmed by scanning electron microscopy. The compressive strength increased from 0.507 MPa to 3.021 MPa, and the compressive modulus (E) increased from 15 MPa to 123 MPa as the density increased from 0.103 g cm À3 to 0.305 g cm À3. Dynamic mechanical analysis revealed that the CE/EP foams possessed a high glass transition temperature (T g ) (203 C) and that density had only a little impact on T g . Moreover, the excellent thermal stability presented with the onset of weight loss taken at 5% value was above 320 C, and the residual weight of the foam was more than 21.6% at 800 C. With increase in the density of CE/EP foams, the dielectric constants (") gradually decreased. For the foam with density of ¼ 0.162 g cm À3 , the value of " was as low as 2.28 at the frequency of 10 kHz.

“…However, for their use as matrix resins for structural composites an increase in toughness would still be required. High-T g amorphous thermoplastics (TPs) have been shown to toughen cyanate esters [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. Commercial types of polysulphone or polyetherimide can be used, but due to the high molecular weight of all commercial TPs, this is at the expense of a large increase in viscosity of the cyanate-TP blend.…”

“…Cyanate ester/epoxy resins, a kind of the composite resins, have been widely used in the high frequency substrates [7][8][9]. Epoxy resin contributed the prominent toughness and adhesion to copper [10,11]; cyanate ester contributed the low dielectric constant, low dielectric loss, excellent thermostability [12][13][14][15][16][17] and low water absorption [18,19]. Besides, it was suggested that it need to increase the composition of epoxy resin in the cyanate ester/epoxy composite resin for better toughness [20].…”

With the prohibition use of lead-solder, the reflow temperature was brought up to about 250 °C. The higher soldering temperature requires the substrate resins with better thermostability and higher glass transition temperature. The cyanate ester/epoxy composite resins are widely used in high frequency substrates for their excellent performance, such as low dielectric constant, low water absorption, high thermostability and dimensional stability. However, the glass transition temperature of the resin is generally less than 200°C. For better performance of the substrate in lead-free reflow soldering process, resins with improved glass transition temperature are required. In this paper, a multifunctional epoxide with a rigid triazine ring, 2,4,6-tris(4-glycidyloxy phenyl)-1,3,5-triazine (TGPT), was synthesized and used to make a composite resin with biscyanatophenylpropane in the mass ratio of 50%. 1-(2-Cyanoethyl)-2-ethyl-4-methylimidazole (2E4MZ-CN) was used as accelerator. The thermal and mechanical properties of the composite resin were characterized by dynamic mechanical analysis (DMA) and thermomechanical analysis (TMA). The glass transition temperature (Tg) of the composite resin was 280°C (tan ) which was much higher than that of the biscyanatophenylpropane/bisphenol A diglycidyl ether composite resin (162°C, DSC). The storage modulus and coefficient of thermal expansion (CTE) of the resin was 3.0 GPa and 55.36 ppm/°C, respectively. Besides, the thermostability of the composite resin was measured by thermogravimetic analysis in the atmosphere of nitrogen. The 5% and 10% weight-loss temperature of the resin were 336°C and 348°C, respectively.
