Abstract
Cationic polymerization of mono and polyfunctional benzoxazine monomers is described. The chemical structure of the polymers from cationic polymerization of benzoxazine monomers has been identified and distinguished from thermally polymerized products from the same monomers. The controllable microstructure of the polymers from benzoxazines prepared by cationic polymerization offers opportunities to prepare and optimize the polymer structure for specific applications.
