Product Details

BAPP CAS 13080-86-9 for Processable Polyimide Synthesis

2,2'-Bis(4-aminophenoxyphenyl)propane, commonly known as BAPP, is an ether-containing aromatic diamine monomer used as a structural building block in high-performance polyimide, polyamide and specialty polymer synthesis. Its aromatic backbone, flexible phenoxy linkages and propane-centered structure make BAPP relevant to polymer systems where thermal resistance, solubility, processability, flexibility and film-forming behavior need to be balanced.

BAPP 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 processable, flexible, 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.
Phenoxy linkages may help improve chain mobility, solubility and film-forming behavior depending on the paired dianhydride and polymer architecture.
Aromatic backbone may support thermal resistance and mechanical performance in selected high-performance polymer systems.
BAPP 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 BAPP with Dianhydride Monomers

In polyimide synthesis, BAPP 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 BAPP in Polyimide Systems

BAPP 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 aromatic structure and phenoxy linkages can influence solubility, polymer morphology and processing behavior.

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