  • Directly photodefinable polymer compositions and methods thereof
    Patent number: 8053515
    Abstract: A polymer includes a first type of repeat unit represented by Formula I: where X is selected from —CH2—, —CH2—CH2—, or —O—; m is an integer from 0 to about 5; and where for the first type of repeat unit one of R1, R2, R3, and R4 is one of a maleimide containing group and for the second type of repeat unit one of R1, R2, R3, and R4 is a hindered aromatic group, a C8 or greater alkyl group, a C4 or greater halohydrocarbyl or perhalocarbyl group, a C7 or greater aralkyl group, or a heteroatom hydrocarbyl or halohydrocarbyl group.

  • Polyimides for use as high refractive index, thin film materials
    Publication number: 20050065278
    Abstract: New compositions for use as high refractive index layers are provided. The compositions comprise a polyimide dispersed or dissolved in a solvent system. The polyimide can be prepared from commercially available dianhydrides and diamines. Preferred polymer include recurring monomers selected from the group consisting of The inventive compositions can form strong, thin films and have high refractive indices making them useful in a wide range of optical applications.
