Product Details

TPE-R CAS 2479-46-1 for Processable Polyimide Synthesis

1,3-Bis(4-aminophenoxy)benzene, commonly known as TPE-R, is an ether-containing aromatic diamine monomer used as a structural building block in high-performance polyimide, copolyimide and specialty polymer synthesis. Its meta-linked phenylene ether structure and dual amine functionality make TPE-R relevant to polymer systems where processability, flexibility, thermal resistance and film-forming behavior need to be balanced.

TPE-R belongs to the broader category of polyimide diamine monomers and is also part of Aure Chemical’s polyimide diamine monomers supply portfolio. It is often considered in flexible, processable, heat-resistant and specialty polyimide material development, depending on the paired dianhydride, formulation and processing conditions.

Molecular Structure

Key Features in Polyimide Design

Ether-containing aromatic diamine structure, relevant to flexible and processable polyimide diamine monomers.
Meta-linked phenylene ether structure may help reduce chain packing and improve solubility depending on the paired dianhydride and polymer architecture.
Phenoxy linkages may support chain mobility, processability and film-forming behavior in selected polyimide systems.
TPE-R can be considered in flexible and processable polyimide systems where solubility, processing and material toughness are important.
Final material properties depend on monomer purity, dianhydride selection, solvent system, imidization conditions and polymer processing method.

Pairing TPE-R with Dianhydride Monomers

In polyimide synthesis, TPE-R may be evaluated with selected polyimide dianhydride monomers to design flexible, processable and heat-resistant PI systems. Ether-containing dianhydrides such as ODPA CAS 1823-59-2 may further support processability and film-forming behavior.

Rigid aromatic dianhydrides such as BPDA CAS 2420-87-3 or BTDA CAS 2421-28-5 may be considered when thermal resistance and dimensional stability are important, while fluorinated dianhydrides such as 6FDA CAS 1107-00-2 may be evaluated when optical, dielectric or moisture-related properties are part of the target polymer design.

Application Context of TPE-R in Polyimide Systems

TPE-R is typically used as a structural diamine monomer rather than a finished application material. It is commonly discussed in flexible, processable, heat-resistant and specialty polyimide material development, where phenoxy linkages and meta-oriented aromatic structure can influence solubility, polymer morphology and processing behavior.

Flexible and processable polyimide systems – solubility, chain flexibility and film formation considerations.
High-temperature polyimide applications – thermal resistance and high-performance polymer environments.
Electronics and semiconductor polyimide applications – insulation, dielectric behavior and electronic material requirements.
Specialty functional polymer materials – ether-containing diamine selection for advanced polymer research.
