| Classes of polymers used in integrated optics include acrylates, polyimides, polycarbonates, and olefins. |
|
| Some polymers, such as most polyimides and polycarbonates, are not photosensitive and are typically processed using photoresist patterning and reactive ion etching. |
|
| Thermoset polyimides, like DuPont's Kapton film and Vespel shapes, also compete in this market area. |
|
| Water-soluble polyimides are needed which can be applied as a coating using aqueous solutions rather than organic solvents. |
|
| Aromatic polyimides having axially dissymmetric 2,2' bis biphenyl units. |
|
| High heat resistance and dimensional stability are claimed for the latest member of SABIC Innovative Plastics' Extem UH family of thermoplastic polyimides. |
|
| The aerospace and electronics industries depend on polyimides because these polymers possess exceptional strength and remain stable at high temperatures. |
