“…Therefore, it needs to be reduced molecular weight to improve the compatibility and processing performance of polyphenylene ether materials with other resins. [6][7][8] The hydroxyl content of low-molecular-weight polyphenylene ether is higher than that of high-molecular-weight polyphenylene ether, and its reactivity is also improved. Therefore, a great interest has been developed on a linear macromonomer or prepolymer with a number average molecular weight of 1000-5000 over the past decades.…”

“…However, high‐molecular‐ weight PPE has some shortcomings, such as poor process‐ability, high‐melt viscosity and low reactivity. Therefore, it needs to be reduced molecular weight to improve the compatibility and processing performance of polyphenylene ether materials with other resins 6–8 . The hydroxyl content of low‐molecular‐weight polyphenylene ether is higher than that of high‐molecular‐weight polyphenylene ether, and its reactivity is also improved.…”

To explore high thermal properties, low dielectric constant and loss for copper clad laminates, poly(phenylene oxide) (PPE) with different end groups (allyl and epoxide groups) were successfully prepared. Firstly, low molecular weight polyphenylene ether was synthesized using the redistribution method. Then the polyphenylene ether thermosetting polymers by modifying their terminal hydroxyl groups were reported and their fundamental materials properties were compared. Through property tests and data analyses, it was found that PPE with vinyl end groups had the best performances, especially high glass transition temperature (about 230°C), the thermal conductivity was 0.32–0.38 Wm−1 K−1, low dielectric constant (about 2.5) and low dielectric loss (about 4.4 × 10−3). The possible reason was that the main chain of polyphenylene ether contains non‐polar crosslinkable group (CC). In a word, through properties comparison of thermosets of PPE, the results demonstrated that the materials of all systems were suitable for using as printed circuit boards.

The PPE and PS of lower melt viscosity are completely compatible systems that can be blended in any ratio to significantly improve the melt flow of PPE resin.…”

Core–shell polybutadiene‐graft‐polystyrene (PB‐g‐PS) graft copolymers with different ratios of PB to PS are synthesized by emulsion polymerization. Further, the PB‐g‐PS copolymers are blended with polypheylene ether (PPE) and PS to prepare PPE/PS/PB‐g‐PS blends. The effects of PB‐g‐PS copolymer structure and matrix composition on the morphological, mechanical properties, and deformation mechanism of the blends are studied. The results show that the synthesized submicrometer‐sized PB‐g‐PS copolymer has an excellent toughening efficiency, both the copolymer and PS are introduced into PPE resin to produce a ternary blend which is combined with high toughness and processing properties. The optimum toughening effect on PPE/PS matrix is observed at the core–shell weight ratio of 70/30 in PB‐g‐PS copolymer, and the impact strength of the blends increased from 101 to 550 J m−1. In addition, the dispersion pattern of rubber particles in the matrix gradually changes from uniform dispersion to aggregation as the core–shell ratio of PB‐g‐PS copolymers increases. On the other hand, with the increase of PPE content, the dispersion of rubber particles in PPE/PS matrix is improved, and the deformation mechanism is changed from cracking to a combination of crazing and shear yielding, which can lead to absorb more energy to achieve better toughness.

“…In this paper, we have redistributed high molecular weight PPO with BPA to prepare rPPO of different low molecular weights, which contain defined numbers of hydroxyl groups at their terminal . This rPPO has then been used as a modifier and partial curing agent in epoxy resin systems (E‐51) to prepare PPO/EP mixed resins.…”

Redistributed polyphenylene oxide (rPPO) was synthesized and used to modify epoxy resin for use as high‐frequency Copper Clad Laminates (CCLs). The chemical composition, thermal stability and micro morphology of cured rPPO/(Epoxy resin)EP mixed resin systems were analyzed and their mechanical, thermal conductivity and dielectric properties determined. These results revealed that the molecular weight of rPPO containing 20 wt% bisphenol A (BPA) was greatly reduced, with a number‐average molecular weight of rPPO as low as 2652.7. Cured rPPO/EP mixed resin systems were prepared with improved heat resistance properties, exhibiting a maximum heat weight loss temperature (Td50%) of 421°C, that was 151°C higher than that observed for pure epoxy resin. Scanning results show that reducing the molecular weight of PPO effectively improves the compatibility with E‐51. Broadband dielectric spectrum analysis revealed that the cured rPPO/EP mixed resin systems had a lower dielectric constant (3.76/107 Hz) and a smaller dielectric loss of 2.11 × 10−3/107 Hz than pure epoxy resin. Similarly, composite laminates derived from cured rPPO/EP mixed resin also showed a lower dielectric constant (4.65/107 Hz) and dielectric loss (6.25 × 10−4/107 Hz) than laminates derived from pure epoxy resin.
