    摘要： An improved process and method for the formation of stable intermediate cyclophanes. Embodiments describe a general method for the production of substituted and unsubstituted cyclophanes. The components include a pyrolysis reaction tube that may be electrically heated into which a flowing stream of nitrous oxide with xylene vapor in an optional inert carrier gas at atmospheric pressure. The exit gas is condensed resulting in the deposition of [2,2′]paracyclophane. Additionally a process and method whereby the reactive intermediates of the reaction described above can be directly deposited and polymerized at atmospheric pressures or thereabout is disclosed.

    摘要： Carbon nanotube (CNT) yarns and sheets having enhanced mechanical strength using infused and bonded nano-resins. A CNT yarn or sheet is surface-activated to produce open bonds in the CNT walls prior to resin infusion. The CNT yarn or sheet is infused with a low viscosity nano-resin that penetrates spaces between individual CNTs and is cured to cross-link and chemically bond to the CNT walls, either directly or through a functional molecule, to bond the individual CNTs or ropes to each other. The nano-resin can comprise dicyclopentadiene having an uncured viscosity near that of water. The cross-linking process involves ring-opening metathesis polymerization and catalysis of the nano-resin in combination with a functionalizing material such as norbornene, to enhance bonding between the carbon and nano-resin. The process increases load capability, tensile strength, and elastic modulus of the yarns and sheets, for use as a structural component in composite materials.

    摘要： In an isoolefin-diolefin rubber production process (e.g. a butyl rubber production process), the cold rubber slurry produced in the reaction vessel is transported from the reaction vessel to the flash tank during which time the cold slurry may be expressed to separate at least part of the cold liquid reaction medium from the isoolefin-diolefin rubber. The separated cold liquid reaction medium is transported off stream, for example by a mechanical filter, where it can be recycled back into the reaction vessel and/or where it can be used to cool a feed stream or streams of the reaction components. The isoolefin-diolefin rubber and the residual liquid reaction medium are transported to a flash tank for further processing. The ability to separate and recycle cold liquid reaction medium makes the process more economical. In one aspect, the slurry may be transported from the reaction vessel to the flash tank by a self-cleaning fully intermeshing co-rotating twin screw extruder, which helps overcome the problem of plugging due to rubber sticking to the surfaces of the slurry transfer apparatus.
