摘要/Abstract

摘要： 采用二苯醚单体合成的含有羟基的新型改性聚苯醚(modified polyphenylene ether, MPPE)可直接作为环氧树脂的固化剂和改性剂. 运用傅里叶变换红外光谱对聚苯醚结构进行了表征, 对MPPE/E51 体系的性能进行了研究. 结果表明: 随着E51 含量的增加, 体系的固化温度降低; 随着MPPE 含量的增加, 体系的热分解温度(T_d5%) 明显升高; 当MPPE 含量为E51的2 倍时, MPPE/E51 层压板具有较低的介电常数(3.51, 1 GHz)、介电损耗(0.008 9, 1 GHz) 和吸水率; MPPE/E51 层压板体系具有较高的冲击强度, 最高可达63.34 kJ/m².

Abstract: As a curing agent and modified agent of epoxy resin, modified polyphenylene ether (MPPE) containing hydroxyl group was synthesized, and characterized by Fourier transform infrared spectroscopy (FTIR). The properties of MPPE/E51 were investigated, and the following results were obtained. The curing temperature is gradually decreased with the increase of content of E51. Thermal stability of the epoxy resin thermosets is improved with the maximum T_d5% being 385 °C. The laminated sheet of MPPE/E51 has low dielectric constant (3.51, 1 GHz), dielectric loss (0.008 9, 1 GHz) and low water absorption. Impact strength of MPPE/E51 is up to 63.34 kJ/m².
