Problems solved by technology

However, when an acid anhydride curing agent is used in combination with an epoxy resin, there is a problem of reactivity: without adding an accelerator, the reaction conditions are harsh and require a high reaction temperature, but the reaction at room temperature is very fast with the addition of an accelerator. Both processability and storage are seriously affected
However, this patent uses the hydroxyl group on the hydroxyl modification agent or the newly generated carboxyl group after the modification reaction as the curing functional group to cure the epoxy resin, which will generate secondary hydroxyl groups during the curing process, which will deteriorate the dielectric properties of the cured product. , that is, the dielectric constant and dielectric loss increase, which is not conducive to its application in high-frequency and high-speed printed circuit board materials
