Bis(aniline) compounds containing multiple substituents with carbon-carbon triple-bonded groups
The invention relates to bis(aniline) compounds containing multiple arylethynyl, alkylethynyl, ethynyl groups or their combinations, processes of making such compounds and materials comprising such compounds. Such, bis(aniline) compounds preferably comprise multiple phenylethynyl (PE) groups, i.e. 2-4 PE moieties. Such compounds are useful monomers for the preparation of polyimides, polyamides and poly(amide-imides) whose post-fabrication crosslinking chemistry (i.e. reaction temperature) can be controlled by the number of PE per repeat unit as well as finding utility in thermosetting matrix resins, 3D printable resins, and as high-carbon-content precursors to carbon-carbon composites.

Metal Supported Powder Catalyst Matrix And Processes For Multiphase Chemical Reactions
A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.
