Collection: Polybenzoxazole Raw Materials

Polybenzoxazole Raw Materials — includes bis(2-aminophenol) monomers and carbonyl dichlorides as well as dicarboxylic acids, which serve as building blocks for synthesizing polybenzoxazole through condensation and thermal cyclization reactions. The combination of amine-hydroxyl groups and these carbonyl groups enables the formation of polymer chains with high thermal resistance.

Polybenzoxazole Raw Materials are used by polymer and aerospace materials researchers to prepare polyamide-imide precursors that are converted into polybenzoxazole through stepwise heating, producing films and fibers with high heat resistance and mechanical strength. Bis(aminophenol) monomers and aromatic dicarboxylic acids are selected according to the target structure to achieve varied thermal properties and solubility of the final polymer for electronic applications and heat-resistant coatings.

Example products in this collection: TCI A0161 124-04-9 Adipic Acid, TCI B6873 1102-92-7 4,4'-(Perfluoropropane-2,2-diyl)dibenzoyl Chloride, TCI B4429 1220-78-6 2,2-Bis(3-amino-4-hydroxylphenyl)propane, TCI D0545 110-99-6 Diglycolic Acid, TCI B2859 7545-50-8 Bis(3-amino-4-hydroxyphenyl) Sulfone, TCI D1888 16523-31-2 4,6-Diaminoresorcinol Dihydrochloride, TCI B2692 20638-07-7 9,9-Bis(3-amino-4-hydroxyphenyl)fluorene, TCI D2088 4194-40-5 3,3'-Diamino-[1,1'-biphenyl]-4,4'-diol.

Pay attention to monomer purity, salt forms (for example dihydrochloride), and the reactivity of acyl chloride groups, which hydrolyze easily and therefore require moisture-free handling during storage and synthesis. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
