Preparation, characterization and curing properties of epoxy-terminated poly(alkyl-phenylene oxide)s

Preparation, curing properties, and phase morphology of epoxy-novolac resin/multiepoxy-terminated low-molecular-weight poly(phenylene oxide) blend

“…As shown in Fig. , E of blends are much smaller than that of EPN, indicating that PPO or modified PPO could be catalysts of the curing reaction to some extent . Moreover, E ‐value first decreases and then increases with an increase of PPO or modified PPO fraction, implying the increase and decrease of curing rate at low and high PPO or modified PPO content, respectively.…”

“…However, owing to their inferior thermal and dielectric properties , the applications of epoxy resins in the high‐performance electronic products that request fast transportation speed and high circuit density are restrained. On the other hand, poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO), a typical engineering plastic, has a low dielectric constant (2.5) and a low dissipation factor (0.0007), and thus it is a good candidate as low dielectric and low dissipation materials . Therefore, blending epoxy resins with PPO have been considered as a feasible and convenient way to obtain a kind of high‐performance electrical materials, for example, high‐frequency substrates.…”

“…To produce the epoxy resin/PPO blend with the controlled phase morphology and high physical performances, the chemical functionalization of PPO chains is adopted. The functional groups such as epoxide , fumaric acid , and (di‐ n ‐butylamino) methyl have been attached to PPO chain ends or its backbones. Till now, the effects of terminal modification of PPO and reactive blending on the phase morphology of epoxy resin/PPO blends are far from being well understood.…”

“…To improve the solvent resistance and thermal stability, some research effort has been directed in the last decade to modifying the properties of PPO from thermoplastic to thermosetting while maintaining its excellent physical properties (Matsumoto et al, 2005;Nunoshige et al, 2008;Fukuhara et al, 2004;Su et al, 2010;Wang et al, 2007).

Molecular simulation of miscibility of poly(2,6‐dimethyl‐1,4‐phenylene ether)/poly(styrene‐co‐acrylonitrile) blend with the compatibilizer triblock terpolymer SBM

“…Although the structure of PPE is simple when compared with other aromatic polymers, it allows many modifications in both aryl and benzyl positions: (1) electrophilic substitution on the benzene ring, (2) radical substitution of the hydrogen from the methyl groups, (3) nucleophilic substitution of the bromomethylated PPE, (4) capping and coupling of the terminal hydroxyl groups in PPE chains, and (5) metalation of PPE with organometallic compounds [2, 3]. It is one of the potential materials that satisfy the demand for high frequency substrates in electronics industry due to its low moisture absorption, excellent electrical insulation property, and dimension stability [4].…”
