| titleOfInvention | It is a kind of to contain trifluoromethyl and oligomeric silsesquioxane structure hybridization polyimides and preparation method thereof simultaneously |
| abstract | Contain trifluoromethyl and oligomeric silsesquioxane structure hybridization polyimides simultaneously the present invention provides a kind of, preparation method are as follows: first by 4,4 '-diphenyl ether tetracid dianhydrides and the aromatic diamine monomers polycondensation of structure containing trifluoromethyl prepare polyimide polymer of the end group containing acid anhydride structure, the oligomeric silsesquioxane Monofunctional monomers of the based structures containing monoamine are added, further polycondensation obtains simultaneously containing trifluoromethyl and oligomeric silsesquioxane structure hybridization polyimides.Such has high dissolubility and excellent film forming containing trifluoromethyl and oligomeric silsesquioxane structure hybridization polyimides simultaneously, made hybridized polymer film has excellent dielectric properties, hot property and optical transparence, has a good application prospect in fields such as electric insulation, microelectronics, gas separation membranes. |
