Problems solved by technology

However, there are also some disadvantages: (1) Reactive groups are limited, especially the content of unsaturated double bonds is low
Because maleic anhydride is used as an end-capping agent, the amount of maleic anhydride is very small; (2) The content of polyetherimide resin (HPEI) in the system is low (≤10%), resulting in the adhesive system Limited improvement in thermal resistance of
