Phosphorus-containing active ester compound and preparation method therefor |
| abstract |
Disclosed are a phosphorus-containing active ester compound and a preparation method therefor. The circuit board produced using the phosphorus-containing active ester compound as a curing agent has excellent flame retardancy and low dielectric constant and dielectric loss. Further, the phosphorus-containing active ester compound has a simple preparation process, is easy to implement, and can be used in large-scale production. |
