• DINADIC PHENYL AMINE REACTIVE ENDCAPS

  公开号：US20080300374A1

  公开（公告）日：2008-12-04

  Dinadic phenyl amine reactive endcap monomers for application in high-temperature polymeric composites are described. The amine group of the endcap is directly reacted with a desired chemical backbone to provide the preferred rigidity and chemical resistance. The ability of the amine group to react with a wide variety of chemical backbones allows the tailoring of formulations for various application temperatures, mechanical properties, processes and resistances while retaining the high degree of crosslinking that yields excellent temperature stability, ease of processing and the necessary toughness. Polyimide oligomers comprising the reaction product of at least one dinadic phenyl amine endcap monomer and a chemical backbone, preferably with a molecular weight not exceeding about 1000-3000, suitable for high-temperature composites are described. The dinadic phenyl amine endcaps may be reacted with an acid anhydride capped precursor to form polyimide resins suitable for high-temperature composites.

  公开（公告）日：2008-12-25

  A process for synthesizing formulations for polyimides suitable for use in high-temperature composites in which all reactions other than chain-extension have already taken place prior to making a composite is described, wherein the resulting oligomers comprise a backbone and at least one difunctional endcap. The resulting resin systems have only the single step of endcap-to-endcap reactions during composite processing. Prior to the initiation temperature of these endcap-to-endcap reactions, the resins are stable affording the composite manufacturer a very large processing window.

  A polymer which comprises recurring units derived from at least one monomer (M) having a general formula (I) Y 1 —Z 1 -Q-Z 2 —Y 2 wherein Y 1 and Y 2 , equal or different from each other, are independently selected from a group consisting of OH, SH, Cl, Br, NO 2 or I; Z 1 and Z 2 , equal or different from each other, independently comprises at least 1 aromatic ring and, Q comprises at least one hydrophilic moiety (H) selected from the group consisting of a sulfone (SO 2 ), a ketone (CO), a phosphine oxide (PO), an ether, a thioether, an ester, an anhydride, a carbonate, an amide, an imide, an imine and an urethane group, and the interatomic distance between Y 1 and Y 2 is at least 10 Å, the monomer has an EC 50 response value to the estrogen receptor a (ERα) equal to or at least 26000 nM.
• NANOMODIFIED BACKBONES FOR POLYIMIDES WITH DIFUNCTIONAL AND MIXED-FUNCTIONALITY ENDCAPS

  Polyimides containing a backbone with at least one nanoparticle component and made from oligomers having endcaps that are difunctional or a mix of di- and monofunctionality are provided. The endcaps may be nadic or phenylethynyl. The backbone may be wholly inorganic or made from a mixture of inorganic and organic groups. The oligomers may be created in-situ using standard polymerization of monomeric reactants chemistry using a solvent or may be provided as a pre-imidized compound that may be either a solid or liquid. It is believed that the nanoparticle component of the polymer backbone provides superior thermo-oxidative stability verses unmodified organic backbones. It is further believed that providing difunctional or a mixture of di- and monofunctional endcaps allows for increased crosslinking to provide improved strength and stiffness verses wholly monofunctional endcapped oligomers for polyimides. The nanoparticle is part of the backbone of the polymer and not solely a pendant group.
