Abstract
The invention relates to a Bismaleimide-Triazine resin (BT resin ) and production method thereof and in particular, a series of novel BT resin prepared by reacting a novel bismaleimide with various aromatic cyanate esters. By combining said novel bismaleimide monomer with various proportions of cyanate esters having different structures, BT resins having various processing temperature conditions can be formulated, which, after polymerizing and crosslinking, can provide materials with various thermal stability, dielectric constants, and mechanical properties for various applications.
