Discover Aure Chemical's High-Quality 3,4'-ODA
3,4'-Oxydianiline (3,4'-ODA), CAS 2657-87-6, is a
polyimide diamine monomer
with a flexible ether linkage and an asymmetric structure, enabling the synthesis of polymers with balanced thermal stability, flexibility, and processability.
Its unique 3,4'-substitution pattern enhances solubility and reduces crystallinity compared to 4,4'-ODA, supporting
flexible and processable polyimide systems
and making it valuable for
specialty functional polyimide materials .
