    Abstract: A process for producing a nanoporous polymer film of no greater than 10 micron thickness having low dielectric constant value, comprising the steps of: (a) providing a polymer in a solution with at least two solvents for the polymer in which a lowest boiling solvent and a highest boiling solvent have a difference in their respective boiling points of approximately 50°C or greater; (b) forming a film of the polymer in solution with at least the two solvents on a substrate; (c) removing a predominant amount of the lowest boiling solvent; (d) contacting the film with a fluid which is a non-solvent for the polymer, but which is miscible with the at least two solvents to induce phase inversion in the film; (e) forming an average pore size in the film in the range of less than 30 nanometers.
    The present invention is also nanoporous films made by the above process.

    Abstract: Micro-sized particles having a polymeric structure of cells are provided. Also provided is a method of producing micro-sized particles having a polymeric structure comprising: (1) forming a homogenous solution by heating a mixture of a high molecular weight polymer and a low molecular weight material, wherein said low molecular weight material makes up at least about 50% by weight of the homogenous solution, (2) forming a dispersed solution by dispersing the homogenous solution formed in step (1) into an inert material, (3) cooling the dispersed solution to cause the high molecular weight polymer to phase separate from the low molecular weight material, (4) forming solid particles comprised of said low molecular weight material trapped inside a structure of cells of said high molecular weight polymer, and (5) removing the solid particles from the dispersed solution.

    Abstract: Porous cross-linked polyimide-urea networks are provided. The networks comprise a subunit comprising two anhydride end-capped polyamic acid oligomers in direct connection via a urea linkage. The oligomers (a) each comprise a repeating unit of a dianhydride and a diamine and a terminal anhydride group and (b) are formulated with 2 to 15 of the repeating units. The subunit was formed by reaction of the diamine and a diisocyanate to form a diamine-urea linkage-diamine group, followed by reaction of the diamine-urea linkage-diamine group with the dianhydride and the diamine to form the subunit. The subunit has been cross-linked via a cross-linking agent, comprising three or more amine groups, at a balanced stoichiometry of the amine groups to the terminal anhydride groups. The subunit has been chemically imidized to yield the porous cross-linked polyimide-urea network. Also provided are wet gels, aerogels, and thin films comprising the networks, and methods of making the networks.
