Process for manufacturing polybenzoxazine monomer for thermal protection
The granted patent US12065415B2 outlines a novel process for manufacturing a polybenzoxazine monomer through the condensation of a specific amine (formula A) with a polyaldehyde (formula B), resulting in the formation of the polybenzoxazine monomer (formula C). The claims detail various conditions and configurations for the process, including scenarios where the amine has no substituents (na=0) and where the polyaldehyde includes a substituted or unsubstituted benzene ring. Additionally, the patent specifies that the integer N1 can be set to 2 or 3, with a particular emphasis on N1 being equal to 2 in some instances.
Further claims expand on the application of the polybenzoxazine monomer in creating crosslinked products. The process includes crosslinking the polybenzoxazine monomer (formula C) either alone or in combination with other monomers, such as a monobenzoxazine (formula D) or another polybenzoxazine (formula E). The patent also describes the use of the crosslinked product in the manufacturing of specialized components, including thruster nozzles and atmospheric reentry bodies, indicating its potential utility in advanced materials for aerospace applications.
