“…Recently, maleimide-modified [22][23][27][28] and furan-modified [29] azines have been synthesized, and the properties of the cured resins have been investigated. Nanocomposites using benzoxazines also recently have been reported [30][31][32][33]. We also have already investigated the curing behavior of the bisphenol-A, terpenediphenol or poly(pvinylphenol) based benzoxazines with epoxy resin or bisoxazoline and the properties of the cured resins [34][35][36][37][38][39][40][41].…”

Abstract. Curing reaction of bisphenol-A based benzoxazine with cyanate ester resin and the properties of the cured thermosetting resin were investigated. The cure behavior of benzoxazine with cyanate ester resin was monitored by model reaction using nuclear magnetic resonance (NMR). As a result of the model reaction, the ring opening reaction of benzoxazine ring and thermal self-cyclotrimerization of cyanate ester group occurred, and then the phenolic hydoroxyl group generated by the ring opening reaction of benzoxazine ring co-reacted with cyanate ester group. The properties of the cured thermosetting resin were estimated by mechanical properties, electrical resistivity, water resistance and heat resistance. The cured thermosetting resin from benzoxazine and cyanate ester resin showed good heat resistance, high electrical resistivity and high water resistance, compared with the cured thermosetting resin from benzoxazine and epoxy resin.

“…By incorporating it into epoxy resin, it is believed that POSS is capable of reducing the high CTE of epoxy resin. The incorporation of POSS molecules is reported to enhance thermal stability, [4][5][6][7][8][9] dielectric property [10,11] and also leads to a good optical transparency. [6] These favorable properties make POSS a promising filler candidate for underfill application.…”

Advanced underfill material plays an important role in device reliability by distributing the thermal stress and providing environmental protection. Recently there is an increasing demand for low stress underfill which requires low coefficient of thermal expansion (CTE), low modulus and good flowablity. In this report, polyhedral oligomeric silsesquioxanes (POSS) functionalized with epoxy groups are used as potential CTE reducing fillers due to their ability to participant in the polymerization reaction. It was found that the POSS/epoxy composite shows excellent high temperature performance, including the increased Tg, lowered CTE and high storage modulus above Tg, and good thermal stability. Moreover, the effects of the length of organic moieties on the chemical and thermomechanical properties of POSS/epoxy composite were systematically investigated.

“…Indeed, POSS coarse self-aggregation and phase separation into crystalline domains are commonly reported in literature [19][20][21][22][23][24][25][26][27][28] and widely prevent its nanometric dispersion in the polymer matrix. POSS molecules seem to prefer to aggregate or crystallize, thus forming organized structures which can reach µm-size dimensions in the polymer matrix (Zheng et al [19]).…”

“…Transmission electron microscopy micrographs and WAXD patterns showed silica aggregates micrometrically dispersed in the matrix. Lee et al [28] prepared a new class of polybenzoxazine/POSS hybrids, characterized by a network structure, by reacting multifunctional POSS with benzoxazine monomers at various compositional ratios. For these pairs, atomic force microscopy (AFM) data showed the presence of POSS aggregates having larger dimensions at higher POSS contents: silica-rich domains in the range of 50-1000 nm were clearly evident.…”

Preparation of inorganic-organic hybrids made of polyhedral oligomeric silsesquioxanes (POSS) and polyamide 6 (PA6) has been attempted either by melt mixing of the two components or by in-situ polymerization of -caprolactam (CL) in presence of POSS. The samples have been characterized by wide angle X-ray diffraction (WAXD) and scanning electron microscopy (SEM) techniques. Specific processing conditions (namely, high T in presence of different shear stresses) have been tested. Two different approaches for melt mixing have been used and the morphology of the corresponding systems compared. The melt-mixed pairs prepared in the microcompounder revealed a coarse phase separation, while those made in a simple mixer did not show any perceivable POSS segregation phenomenon, as evidenced by both WAXD data and SEM investigation. Similarly, the in-situ polymerization of CL in presence of POSS did not result in any POSS self-aggregation in the polyamide matrix, achieving a very fine Si dispersion of nanometric dimensions.
