Description

technical field

[0001] The invention belongs to the field of polymer synthetic materials, and in particular relates to a double-terminated phthalonitrile-benzoxazine resin, a cured product and a preparation method thereof. Background technique

[0002] Thermosetting phthalonitrile polymer is a new type of thermosetting polymer material. It is a high-temperature-resistant polymer material with great application potential in the fields of aerospace, ships, and electronic packaging materials. Its heat-resistant temperature can be as high as 350 ℃. It can prepare resin-based composite materials, high-temperature-resistant adhesives, electronic conductors, semiconductors, and organic magnetic functional materials, which have functional characteristics such as corrosion resistance, radiation resistance, and high strength. The existence of these performance and functional characteristics will make it have a wide range of application prospects. J.Polym.Sci., part A: Polym.Chem.37,...
