Descripción general
Pyromellitic dianhydride is a dianhydride class of monomers commonly used in the preparation of polyimides polymers which are used in aerospace, electronics, and automotive industries because of their excellent thermal stability, high mechanical strength, and inherent flame resistance. It is also used in the synthesis of thermoplastic polymers such as polyesters and polyethers, as well as plasticizers and epoxy resins. Additionally, PMDA serves as a curing agent for epoxy resins. Epoxy resins are widely used in adhesives, coatings, composites, and electrical insulation materials.
Pyromellitic dianhydride (PMDA) is an acidic anhydride that can be used as a repair agent and as a chain extender in the formation of polyethylene terephthalate (PET) based chain extensions. It is mainly used in the production of thermoplastics and other coating applications.

Aplicación
PMDA can be used as:
- A monomer to synthesize aromatic polyimides with excellent thermo-mechanical and chemical properties. These polymers find the applications in automotive and electronic industries.
- A capping agent in the development of siloxane-based hybrid materials for potential usage in organic electronics.
- A monomer in the preparation and modification of thin film composite membranes, which are used in water purification, gas separation, and biomedical devices.
- A monomer in the synthesis of pyromellitic diimide-based copolymers as stable cathode active materials for lithium and sodium-ion batteries.

A series of zwitterionic hybrid polymers were prepared from the ring-opening polymerization of pyromellitic acid dianhydride (PMDA) and phenylaminomethyl trimethoxysilane (PAMTMS), and a subsequent sol-gel process. FTIR spectra confirmed the step products. TGA analysis showed that the thermal degradation temperature

Electrospun beta-cyclodextrin (βCD)-based polymers can combine a high surface-to-volume ratio and a high loading/controlled-release-system potential. In this work, pyromellitic dianhydride (PMDA)/βCD-based nanosponge microfibers were used to study the capability to host a common insect repellent (N,N-diethyl-3-toluamide (DEET)) and to monitor
