Organic-inorganic polybenzoxazine copolymers with double decker silsesquioxanes in the main chains: Synthesis and thermally activated ring-opening polymerization behavior

In this contribution, we reported the synthesis of a series of organic-inorganic polybenzoxazine (PBZ) copolymers with double deck silsesquioxane (DDSQ) in the main chains via Mannich polycondensation. Their thermally activated ring-opening polymerization behavior and thermomechanical properties have been investigated in this work.149
