5. Gas permeability of fluorinated hyperbranched polyimide
The gas permeability of carbon dioxide, oxygen and nitrogen for hyperbranched polyimide (HBPI) containing trifluoromethyl groups were investigated. The H13Pls were prepared by condensation polymerization of a triamine monomer, 1,3,5-tris(2-trifluoromethyl-4-amino-phenoxy) benzene (TFAPOB) and a commercially available dianhydricle monomer 1,4-bis(3,4-dicarboxyphenoxy) benzene dianhydride (HQDPA). W...

3. Fluorinated Hyperbranched Polyimide for Optical Waveguides
A novel fluorinated hyperbranched polyimide (HBPI) is synthesized by using a new triamine monomer, 1,3,5-tris(2-trifluoromethyl-4-aminophenoxy)benzene (TFAPOB) (A3), as a ‘core’ molecule, 4,4-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) as a B2 monomer, and 3,5-ditrifuoromethylphenyl as an endcapping reagent. The polymer shows a glass transition temperature of 232 °C and a temperature ...

Preparation and characterization of polyimide optical compensator used in liquid crystal display units(LCD)
关键字:polyimide, birefringent film, polyimide film, negative birefringence.
Two kinds of polyimides with side-group(-CH3) and their films have been produced. The polyimides produced were soluble in strong polar solvents such as NMP, DMAc and DMF. Compared with conventional polyimide films, the polyimide f...

Flame Retarding Gel Films based on Polyimide Precursors
In spite of their outstanding properties such as high mechanical property and excellent thermal stability, polyimides(PIs) have the disadvantage of poor solubility and high glass transition temperature which make them difficult to process.
