摘要:开发了一种不形成焦油的重氮盐水解新方法.由环戊基甲基醚 (Cpme) 和水组成的两相系统对于重氮盐的水解非常有效.使用该溶剂系统,由 3-(4-硝基苯氧基)苯胺制备的重氮盐在 20 分钟内以高产率 (96%) 得到 3-(4-硝基苯氧基)苯酚.合成的苯酚是工业上合成聚合物的重要原料.此外,使用本 Cpme 和水的两相系统成功地将几种间位取代苯胺有效转化为相应的间位取代苯酚.这是使用两相系统(cpme 和水)水解重氮盐的第一个例子.

摘要:This invention describes resins with phosphate cores and a simple, three-step process for their synthesis. Preferred resins are cyanate ester resins with bridging phosphate groups. These resins can be cured to produce thermoset polymers having Tgs of between 131 and >360° C. depending on the number of cyanate ester groups per phosphate and the substitution pattern of the aromatic rings. The high char yields of these resins, up to about 67%, coupled with the phosphate core means that these materials will have applications as fire-resistant polymers. Additionally, these materials can potentially be blended with conventional cyanate esters or other compatible thermosetting resins to improve the fire resistance of composite materials. Other applications may include use in fire-resistant circuit boards, or as surface coatings to reduce flammability of conventional composite materials or thermoplastics.
