Modified LCP (Liquid Crystal Polymer) material as well as preparation method and application thereof

The invention discloses a modified LCP (Liquid Crystal Polymer) material as well as a preparation method and application thereof, and belongs to the technical field of high polymer material modification. The modified LCP material provided by the invention is prepared from the following raw materials: a chain extender and LCP resin, the chain extender is selected from an epoxy chain extender, and the epoxy chain extender contains two or more than two alicyclic epoxy groups. The specific chain extender is adopted to modify the LCP resin, the viscosity of the LCP material is still improved even if a compatibilizer is not needed, meanwhile, the problems that the chain extender and matrix resin are poor in compatibility and uneven in dispersion are solved, and the modified LCP material is good in film forming performance. 本发明公开了一种改性LCP材料及其制备方法与应用，属于高分子材料改性技术领域。本发明提供的改性LCP材料，包括以下制备原料：扩链剂、LCP树脂；所述扩链剂选自环氧类扩链剂，所述环氧类扩链剂含有两个或两个以上的脂环族环氧基。本发明采用特定的扩链剂对LCP树脂进行改性，即使在不需要增容剂的情况下，仍提高了LCP材料的粘度，同时，解决了扩链剂与基体树脂相容性差、分散不均匀的问题，改性后的LCP
