    Abstract: A class of solvent resistant, flexible copolyimide substrates having high optical transparency (>80% from 400 to 750 nm) that is retained after brief exposure to 300° C., near-zero birefringence (<0.001) and a maximum CTE of approximately 60 ppm/° C. is disclosed. The copolyimides are prepared from alicyclic dianhydrides, aromatic cardo diamines, and aromatic diamines containing free carboxyl groups. The substrates are manufactured from solutions of the copolyimides containing multifunctional epoxides in the form of single layer films, multilayer laminates and glass fiber reinforced composite films. The substrates can be used in the construction of flexible optical displays, and other microelectronic and photovoltaic devices that require their unique combination of properties.

  • Publication number: 20130089716
    Abstract: The invention described herein is directed towards spin-on carbon materials comprising polyamic acid compositions and a crosslinker in a solvent system. The materials are useful in trilayer photolithography processes. Films made with the inventive compositions are not soluble in solvents commonly used in lithographic materials, such as, but not limited to PGME, PGMEA, and cyclohexanone. However, the films can be dissolved in developers commonly used in photolithography. In one embodiment, the films can be heated at high temperatures to improve the thermal stability for high temperature processing. Regardless of the embodiment, the material can be applied to a flat/planar or patterned surface. Advantageously, the material exhibits a wiggling resistance during pattern transfer to silicon substrate using fluorocarbon etch.

  • Publication number: 20130078397
    Abstract: An insulated glass sealant includes an elastomeric matrix that is the reaction product of a carboxyl-terminated polymer and a polycarbodiimide. A method of sealing an insulated glass unit includes applying the insulated glass sealant to one or more glass sheets, a spacer to be disposed between the glass sheets, or both; and contacting the one or more glass sheets with the spacer to define an annular space between the glass sheets and to produce the insulated glass unit. The sealants maintain the excellent attributes of traditional polyurethane sealants, such as low water swell, low moisture vapor transmission, good adhesion to the window frame, low migration of the insulating gas, and good workability, but without the use of polyisocyanates in the curing process. Methods for making the sealant and for sealing insulated glass panels, such as glass windows, with these rugged sealants, and the resulting articles, are also provided.
