Synthesis and comparative study on polyetherimides: This study examines different isomers of 4,4′-Isopropylidenediphenoxy bis (phthalic anhydride) to develop polyetherimides with varied properties, useful in customizing materials for specific industrial applications (Jiang et al., 2021).

Apr 3, 2025 · 4,4'- (4,4'-Isopropylidenediphenoxy)diphthalic Anhydride (BPADA) is a diphthalic anhydride structural unit with a core of bisphenol A. BPADA is a precursor for the synthesis of polyimides, which are highly thermally stable and have strong mechanical properties using their bisphenol A core.

polyetherimine prepared from bisphenol a diether dianhydride (BPADA) monomer is a kind of fusible polyimide, which not only maintains various excellent properties of polyimide, but also has the processing properties of general plastic plastics, and is cheap, suitable for preparing thin-walled products and products with complex structures.

May 12, 2021 · To enhance PI films, SABIC’s new SD1100P BPADA powder offers superior performance properties versus other types of dianhydrides. For instance, the SABIC product delivers lower water absorption, better dielectric performance and metal adhesion compared to oxydiphthalic anhydride (ODPA).

May 17, 2022 · Mixed isopropylidenebis (1,4-phenylene-oxy) bis (phthalic anhydride)s with different ratios (Mixed-BPADA 1-3) were synthesized successfully via aromatic nucleophilic substitution from nitrophthalonitrile and bisphenol A.

Feb 7, 2023 · A series of CPI resins with improved optical properties and melt processability were successfully prepared by copolycondensation of BPADA and TFMB with 6FDA or CBDA via chemical imidization that brought flexible ether bonds, bulky trifluoromethyl groups, and an alicyclic structure into the polymer.
